Multiplayer Challenge Guide

Weapon Challenges:
Shotgun Attachment
Use one man army or scavenger to resupply your grenade ammo, and use
danger close for increased explosive radius

Holographic Sight
Just use red dot sight, no tricks here

Heartbeat Sensor
I would suggest playing hardcore when using silencers, as you only need to
do half the damage so you won’t lose 1v1s as a result of the reduced
damage. Also keep in mind that silencers reduce damage by 40%, and
stopping power increases damage by 40%

Thermal Scope
using acog can be a hassle sometimes, so it is best to use slight of had
pro to allow you to scope in fast to get close to mid range kills. Steady
aim does nothing because you can’t hold your breath for this scope

Extended Mags
40 FMJ kills can be a hassle, so use stopping power. UAVs and heartbeat
sensors can be a blessing for this because you can see where people are
behind walls. Also make note that if you hit someone, an X appears in the
middle of your reticule, so use that to pinpoint targets behind walls.
Another strategy is to shoot at people in the open, while you are behind
the wall. Just line up your shot, then strafe behind a wall or corner and
start shooting. Two more things to make note of is 1, chain linked fences
are considered to be walls, and 2, FMJ still penetrates walls if you bling
it with a silencer.

Riot Shield Challenges
A riot shielder should always carry stun grenades, but the equipment they
use can vary between throwing knife, blast shield, and C4. The best ways
to deflect bullets are sentry guns, and my favourite, harriers.

Perks:
Marathon
This one involves a lot of running. The most important thing to know for
this is that once you press down on the left stick, you can release it and
you will keep running as long as you hold forward. This will save you from
getting sore thumbs. Because this perk takes so much running, you will
want to level it just by having it equip from level 1. This may affect
your precious K/D spread, but it will get you marathon pro VI by level 70.
I would also advise playing as the witch/knife monkey (marathon,
lightweight, commando, non akimbo sub machine gun and .44 magnum with
tactical knife) or use a shotgun with steady aim, as these builds involve
a lot of running. Also keep note that the distance traveled while holding
a care package will not be counted.

Scavenger
Scavenger is most useful when using grenade launchers or rockets, but can
be used on any build. The key to levelling this is to make sure you are
always short something when running around. It is best to equip stun
grenades, and when you come across a pile of dead bodies, spam the stun
grenades. The reason to use stun grenades, is there is 2 unlike smoke, and
flash grenades may hit you when you throw them randomly. Also secondary
equipment is thrown much faster than other items (except throwing knives)
so it is the fastest to resupply with. This is best done in ground war
during domination.

Sleight of Hand
This can really be done with any build, but is most effective with close
quarters combat, such as shotguns and submachine guns. This is also
helpful for large machine guns (aka Party Rifles) because it lets you spam
bullets way more frequently. Once you get to level IV you get the quick
scoping ability as well, which is very useful for sniper rifles and
assault rifles.

Bling Pro
Two attachments? That in itself is how to level it, that is all.

One Man Army
The easiest way to level this is use builds where you won’t need a
secondary weapon. For me this usually involves an assault rifle with
shotgun attachment and steady aim. Once you get level IV the change time
is halved, and you can actually make use of this perk.

Stopping Power
This perk makes you do 40% more damage, with a regular assault rifle doing
30 damage; this means you will only need 3 shots to kill instead of 4.
Also a sniper rifles damage would increase from 70 (all sniper rifles
damage is the same) to 98, not enough to kill someone, but any 1.1
multiplier body part will be a 1 shot kill. Different sniper rifles have
different multipliers for the stomach and chest.

Lightweight
Same situation as marathon, except you need to travel double the distance
to complete level VI.

Hardline
Set your killstreaks to 3-4-5, and keep a semtex or frag grenade handy to
kill yourself every 4 kills. This is best done in free-for-all.

Cold Blooded
There are two ways to do this efficiently. First off is to use this with
scavenger and use the stinger. The second is when you have one man army
and don’t want to have to respawn to shoot stuff down. Make a build with
this, one man army, and a light machine gun (excluding Aug HBar) and just
fire madly at whatever is flying in the air. This is even more effective
if you are screaming while you do it. Just so everyone knows as well, you
can shoot down a UAV, and when you have stopping power pro, it takes less
than a clip of an assault rifle to do. Also, you cannot hit AC130s with
bullets.

Danger Close
Two was to do this. First off is to use scavenger, an assault rifle with
grenade launcher, a secondary launcher, and an explosive piece of
equipment. The second method is to just use an assault rifle with grenade
launcher, one man army, and an explosive piece of equipment.

Commando
Play as the Witch/Knife Monkey. Use marathon, lightweight, non akimbo sub
machine gun, and the .44 magnum with a tactical knife (.44 has the fastest
pull out speed). Run around. Kill people.

Steady Aim
Don’t scope to shoot, which won’t work for long ranges. The most effective
weapons for this are akimbo weapons, so sub machine guns, machine pistols,
pistols, or shotguns (shotguns don’t need akimbo). Easiest done when using
marathon and lightweight or stopping power.

Scrambler
This one can be tricky, as this perk actually gives you a major
disadvantage. When using this, people will be able to tell that you are
coming for them, so I would advise to play team hardcore with counter UAV
as a reward for when they get a UAV. You can get your close range kills
with a CQC weapon, or using the knife (without commando though)

Ninja
Most useful tier 3 perk, especially the pro version for search and destroy
or hardcore game types. Best earned by knifing or using shotguns.

Sitrep
This is definitely one of the hardest challenges in the game to complete.
The first thing to do in order to get this challenge is to realise in what
game types people will use claymores, C4 and tactical insertions in. The
most effective game type I have found is hardcore team deathmatch. Make a
build with a silenced primary weapon blinged with a heartbeat sensor (I
used the M21 EBR when I earned it because it 1 shot kills in hardcore
while silenced). For a secondary weapon use a machine pistol or a pistol
with a silencer and FMJ, as it will still penetrate walls with a silencer
on it. Enter a game, run around looking for claymores and tactical
insertions, and if no one is placing them, leave and look for a new game.
Make sure to not kill anyone if you see claymores on the map, it might be
theirs. If you do kill someone suspected of being the player, you have
anywhere between 1 and 15 seconds before they respawn to destroy it. If a
teammate is going to set off the claymore, shoot him dead before he does.
Use your secondary weapon to shoot things through walls, and make sure not
to kill yourself if they aren’t, as the blast radius is far greater in
hardcore. Once you destroy 750 claymores n stuff, pat yourself on the back
for having no life. It is also possible to shoot grenades to get points to
this challenge.

Last stand
There are 2 initial setups you can use, either equip the .44 magnum so
that you use that when you drop, or don’t because if you are out of ammo
when you drop, you will have to reload while in last stand. Also make sure
to use stopping power, as a pistol does 40 damage, and you want to be able
to 2shot the enemy. The next step is running blindly into combat, or
jumping off tall buildings into enemies, which you then kill while in last
stand. Once this is done, kill yourself by pressing X, and repeat.

Equipment:
Darkbringer
Use sitrep and join in on a capture the flag game. Grenade launchers on
assault rifles, semtex grenades, and FMJ on your secondary weapons are
especially useful. This may take some time, as not many people tactically
insert. Another problem is that people are usually near their tactical
insertion, and if you kill them, they will pop back up removing it. This
is why it is always needed to be done on gametypes with respawn timers.

Tactical Deletion
Use sitrep again, and this time, either kill the person near the insertion
then aim at the insertion, or place a claymore behind the insertion so
when they spawn and run forward, they die. This second tactic is quite
fun, but you need to make sure the claymore is well placed, because it
doesn’t set off until they start moving.

Grenade Kill
For this you could either use martyrdom and hope for the best, walk around
with a semtex in your hand or you could just use one man army or scavenger
and spam grenades of either type. Best done with danger close equip. Also
throwing a stun grenade first can let you know if there is an enemy there,
and make it so they can’t run away.

Plastered
A very difficult challenge in my opinion, I am horrible at sticking
people. If the target sees you already, throw a stun grenade at them
first, and wait a second to see which direction they start to move. If
they don’t see you, throw the semtex without using a stun grenade, as that
will make them panic and move in a random direction.

Carnie
Throwing knifes are easy kills at close to mid range, if you are having
trouble, use stun grenades. Use this with scavenger to replace your knife
if you can’t find it after throwing.

It’s Personal
Best done when sneaking up on someone, but can be done with pretty much
any weapon. Stun grenades work again with this challenge.

Did You See That?
Walk around wielding a knife and waiting to get flashbanged. Once blind,
release bumper, killing whoever you were aimed at.

Claymore Shot
Place claymores beside door entrances aimed 45 degrees towards the door;
stand in room and fire weapon, drawing attention of individuals. If people
are running past your claymores unscathed, skip ahead to the counter
claymore challenge. Best used with danger close, or in hardcore matches.

Jack-In-The-Box
Best used with one man army if you need to replace your tactical
insertion. Best done on small maps and using ninja. Sneak around until you
see an enemy, hide and tactically insert. Next run out wildly shooting
near the enemy, making note of where enemies are. Die, then respawn run
out and kill as many people as you can within 5 seconds. Maximum I have
gotten in any bust is 3. Also make sure to play a gametype with instant
respawns, or else this is very difficult.

Solid Steel
Make a build with riot shield and blast shield, and then enter a game of
headquarters pro. Go to the headquarters and just hide in a corner and sit
there until you die. Stun grenades and commando can be useful for people
who are trying to kill you by not using explosives.

C4 Shot
This is much easier if done with danger close. Play objective based games
and plat C4 in an important location or on a much traveled path. If in a
room, don’t place it directly at the door, as you won’t be able to set it
off until the person is partway in the room anyway, Using care packages as
bait can work as well. Best used with riot shield so you can be in visible
range of the C4 without dying.

Basic Training:
Ghillie in the Mist
Barret 50cal or Intervention with stopping power is your best choice. With
this you can 1shot anyone in any part of their body except a limb. Barret
50 cal has faster refire time, were the intervention has lower recoil, so
your preference of which to use should be based solely on that. Another
option is to also use sleight of hand pro, and use “quick scoping” which
is when you look at an enemy that is really close to you, press left
trigger, then press right trigger, giving you the accuracy of a sniper
rifle at the distances of a few meters.

Crouch Shot
Crouch anywhere on any map. Fire blindly.

Prone Shot
I have never actually gotten this challenge, but my friend did when he
played on my account, as a sniper. A better method for this is the laying
down in 1v1 tactics. When you come around a corner and you and some enemy
start shooting each other, hold B while you shoot. You will lay down which
does 3 things. 1 your enemy will have a smaller target to shoot at from
their view (less person flux in that dimensional plane). 2 you will be
lower than they expect, and if their gun has recoil, aiming down will be
more difficult for them to do then you would expect. 3 you will get kills
towards this challenge.

Point Guard
Easiest way is by just playing the game. Second easiest way is to span
flash grenades all over the map while using scavenger.

X-ray vision
Keep in mind you do not need FMJ to shoot through walls, you just need it
to do more damage through walls or shoot through thicker walls. Complete
this challenge by either going for extended mags, or just shoot people
through small posts all over the map.

Backdraft
If you see things, destroy them via bullets, explosives, or knives.

Goodbye
If doing this over the edge of a map, keep in mind there is an invisible
death floor partway down, and if this is less than 30 feet from where you
are, it won’t count. Finding higher things to fall from is more effective,
as well as jumping off these things.

Base Jump
Fall or jump off things. Best done with commando pro.

Flyswatter
Shoot down a UAV with an assault rifle would be the easiest way.

Vandalism
Aim noob tube at car from a distance. Fire.

Operations:
Free-For-All Victor
Play free for all and get a lot of kills fast. This means always moving
and usually using closer ranged weapons then you are used to.

Team Player
Play deathmatch, win.

Search And Destroy Victor
Play search and destroy and win, wins can be completely independent of
your involvement, but using ninja can help a lot.

MVP Team Deathmatch
Be decent at the game, or hope everyone else sucks.

Hardcore Team Player
Play hardcore team deathmatch, win.

Sabotage Victor
This one takes a while because these games are gruellingly long, and can
end in a draw. Make use of UAVs and claymores in this gametype. Make sure
to have a special build with a silencer, cold blooded and other surprises
for overtime. Keeping a chopper gunner or AC130 for overtime is always a
good idea.

MVP Team Hardcore
Be good at the game. Use ninja or sitrep, run around a lot, and use a
setup where 1-2 bullets will kill someone.

Bomb Down
Place claymores at the bomb planting area then hide.

Bomb Defender/Bomb Planter
Best done while earning the Sabotage or S&D victor challenges

Bomb Defuser/Saboteur
Best done while earning the Sabotage or S&D victor challenges

Last Man Standing
Ender a search and destroy game, choose the scout sniper prebuild, or
something else with cold blooded, and then go grab a snack or beat one off
quickly.

Killstreak:
Regular ones
Earlier ones  can be done easily, mid ranged ones may require hardline,
and the later ones can be a choice from you to either earn them or get
them from crates. Keep in mind you can never get a nuke from a crate, and
you can only get an EMP from a care package, not an emergency air drop.
Inbounds
Keep in mind that all of the inbound III challenges require calling in
1000 shits. This would mean if you had hardline and killed yourself after
getting every 3 kill streak, you would have to play and win 53 free for
all matches to earn radar inbound III. Keep in mind that is an ideal case
where you never die except on purpose.
End Game
Nukes are quite a pristine thing in MW2, except for the fact they call
them into random places frequently. In order to earn a nuke, you need all
the cards to be in your favour, or really really good. This means that you
need: an objective based game, an enemy team of people who don’t seek
revenge by throwing a well placed grenade, and enemy team getting
killstreaks that may take you out (aka stealth bomber), no one else on
your team better than you(to beat you to a nuke). Other situations need to
be thought of too. If you are protecting an area with claymores no one on
the enemy team can have sitrep, or you are garunteed to die. Making your
fortress protected against people who run through claymores as well must
be done. This can easily be done by using one man army to place C4 in
front of all of your claymores, making anyone who comes near your
claymores certain to die. In my opinion you should have one man army on
all of your builds you are using in order to be able to take advantage on
any situation. Killstreaks should be set to harrier-AC130/chopper
gunner-Nuke, the reason you don’t use pavelow is because of a glitch that
makes it not count towards your killstreak 9 times out of 10. Also it is
good to have a build with danger close to switch to when using your
killstreak rewards, as it increases the explosive damage/radius of your
killstreak attacks. Keep in mind this leaves you vulnerable to enemy
killstreak rewards as you pilot your 11 streak rewards. A list of what 11
streak rewards is better for what map is listed below
Afghan – AC130
Derail – AC130
Estate – Both
Favela - Chopper Gunner
Highrise - Chopper gunner
Invasion – Chopper Gunner
Karachi – AC130
Quarry – Both
Rundown – AC130
Rust – AC130
Scrapyard - Both
Skidrow - Chopper gunner
Sub Base – Chopper gunner
Terminal – AC130
Underpass - Both
Wasteland - Both

Assault Expert/SMG Expert/LMG Expert
Equip your favourite weapon of the right type, add a sight if you wish,
and then run around on a flat level never looking up or down.

The Surgical/Mach5/Dictator
I swear these things are impossible, but then again I just never attempted
them. I guess just use cold blooded and a silencer to reduce your damage,
then shoot a couple shots into nearby enemies and hope they don’t notice
you because of it.

Perfectionist
Anyone who doesn’t suck with a sniper rifle should have got this one by
now. Easiest to be done in an objective based game.

Multi-RPG/Clay More
I have yet to get these, Just use danger close and hope you are lucky

Multi-Frag/Multi-C4
Both can be done easily on objective based games using danger close. Make
sure to cook the grenades perfectly, and the C4 can be placed ahead of
time, or just throw it.
Collateral Damage
This is a combination of luck and skill, again best done on an objective
match, also use intervention or barret 50cal with stopping power. An
alternative would be to do it in hardcore.

Flawless
Hide somewhere with ninja and cold blooded. Go take a dump or to the store.

Fearless
Easy if you can snipe well. Killstreaks set to predator
missile/airstrike/harrier. Once you are at 5 you should be able to hide
somewhere and let your killstreaks do the rest.

Group Hug
Stun grenade then semtex. Best done in domination in ground war with
marathon and lightweight, just run across the map at the start of the game
to their flag and stick someone.

NBK
Be a Natural Born Killer.

All Pro
Snipe while standing up in a level playing field. Easiest to be done on
Terminal down the hallway using FMJ. People will spawn in the store in the
back and while shooting someone in front you can get 2 kills. I originally
got this with a pistol in last stand. I’m not really sure what happened
but it was pretty epic.

Airborne
After doing this 10+ times with no challenge getting completed, I gave up.
Not too long after, I got stuck between the path and the cliff on the back
of Afghan, which considered me to be in the air. Surely enough I killed
someone and got the challenge completed. Looking later, there are several
rocks and crannies all over this level that consider you to be in the air,
your character will slide a bit while in them, and your crosshairs will
stay wide open when you aren’t moving. This can also be achieved on the
forklift in Scrapyard in the slightly raised building on one side. Jump on
the barrels in the middle, then jump around the forklift onto its front,
that location works too.

Finishing Moves:
Droppin Crates
This one is both fun and challenging, there are 2 ways to do it. One is to
find an afk person, or a completely oblivious sniper, and throw your care
package marker on them, tah-dah. The second method is far more devious and
difficult. On search and destroy you first must earn a care package (I
suggest hardline and using claymores). Next you must plant the bomb(you
will have to be defending the first 3 rounds for this to work). Then as
someone runs to defuse, you must throw the care package. Once they are
defusing, you must wait about 2 seconds, then throw a stun grenade at them
and shoot them once. This might cause them to stop defusing the bomb,
which is what you want. Throw the second stun grenade when the first
starts wearing off, then he will be crushed by the crate, making everyone
with mikes on both teams laugh uncontrollably; good work. This can also be
done by throwing the care package near a wall earlier as the person may
not notice it when they go to the bomb. The crate can hit the wall and
bounce onto the person. I have not tried this because bouncing crates off
walls is hard, but someone should.

All The Other Ones
Play free-for-all and kick ass at it, use UAV/care package/sentry gun. Get
a 5 kill streak and throw your sentry gun marker somewhere random. Then as
its dropping throw your care package somewhere more convenient and turn on
UAV. This makes everyone go after your sentry gun as you safely acquire
your care package. Continue until you have a rewards you like, then get to
1450 points and use it with a UAV to kill someone. The finishing moves
challenge list was by far the easiest to complete in my opinion.

Unbelievable/Owned/Stickman/Last Resort
These can be done by just suiciding and respawning with a specific build
when at 1450 points. Stickman I found very hard cause my sticky aiming is
atrocious, whereas the other 3 were unbelievably easy.

Humiliation:
Hot Potato
Seeing as nobody throws a frag grenade without cooking it, and the
martyrdom grenades seem to already be half cooked, I thought that this
challenge was going to be impossible. But as luck would have it, your own
grenades work. Yes that’s right kids, just equip a frag grenade, one man
army and danger close. Run around frantically, when you see a possible
target, throw your frag grenade at a nearby wall, run over, pick it up,
aim your shot and throw. It is unbelievably easy and their killcams look
pretty funny.

Car Bomb
If you aren’t getting opportunities to kill people by throwing semtex or
grenade launching cars, there is a foolproof way, but takes a bit of time.
Equip C4 and a riot shield in a build, go into free for all, earn a care
package, and find a car. Switch to this build, place C4 on one side of the
car, and throw your care package at the other. Hide somewhere in sight and
wait for your unsuspecting victim to run up to the care package all giddy.
Once he is laying there, wait a few seconds to give him hope, then set off
your car bomb and take pride in how horrible of a person you are.

Backstabber
Find someone who obviously hasn’t found you and press down on the right
stick, you may need commando if you suck.

Slow But Sure
Hope the enemies have stun grenades and kill them often.

Misery Loves Company
Equip a frag grenade and use lightweight or danger close. Pull out your
grenade when you see a victim and follow them. This can be done by
sneaking up, finding a sniper, or my favourite which is dropping down on
them from above.

Ouch
Run around a close quarters map with your grenade launcher out.

Rival
If you really can’t get this go into third person cage match.

Cruelty
Can be done anywhere but I guess the easiest would be third person cage
match.

Think Fast/Think Fast Stun
Riot Shield stun grenades and a frag grenade. Find someone close, throw
the stun grenade directly at them so it hits them, run up, bash them,
throw the second stun grenade at them, then the frag. This is just enough
to kill them. For the stun, switch the last 2.

Think Fast Flash
This one is harder because you don’t have a stun grenade. The best way is
just to wait until you find someone in last stand and throw it at them.

Return To Sender
Best done using sitrep. Keep in mind you can also shoot some ones grenade,
but that would be difficult.

Blindfire
Get flashed, kill people.

Hard Landing
Kill someone while they are climbing a ladder.

Extreme Cruelty
For brownie points do this in a ground war game, but if you are a pussy,
then you can just join a deathmatch. Use a chopper gunner or AC130 for
best results.

Tango Down
If you are having trouble with this one play sabotage.

Counter MVP
One of the few challenges I don’t have. By killing someone 10 times you
are definitely impacting the number of kills they can get. Also third
person cage match doesn’t count because it is considered to be a
free-for-all game.

Payback:
All of these happen by chance, but if you wish to speed them up, play
third person cage match, though they seem to catch on after about 5
payback kills. This means you may have to leave some games early.

Elite
Master Chef
Equip frag grenade and danger close. Hold the right bumper for a couple of
seconds then release in the direction of the enemy.

Counter Claymore
You will get a lot of these if you try to level sitrep, but for any extras
you need, this is the easiest way. Place a claymore in a room by a door.
Hide in room laying down aimed at said claymore. When you hear the click
of the claymore triggering quickly shoot, the person will die. This is
because claymores have a 1 second response time (or 3 for scrambler pro).

Counter C4
Easiest way is to just use one man army and place a C4 in front of every
claymore you lay, this also increases the reliability of your defence.

The Brink
Be creative, this isn’t hard.

Fast Swap
Pistols do 40 damage without stopping power and 56 with. Also the .44
magnum has the fastest switch-to time, so it would be the one to chose.
The fal does around the same damage too so one shot of each with stopping
power should do the trick.

Star Player
Get 1 kill then hide. The alternative is to just play well. Easily done in
free for all.

How The ?
Two methods, one is by using sitrep you will get this easy. The second is
finding someone afk, then placing C4 near them and shooting it through a
wall. You don’t need FMJ but it could help.

Dominoes
Same method as counter C4 for easiest the way.

Invincible
This is easiest done with marathon and lightweight as you can get in and
out of enemy fire quickly. Also you may want to make use of a turret to do
this. A riot shield can be utilised too.

Survivalist
Hide in a corner with cold blooded and ninja.

Enemy Of The State
Play search and destroy and hide until everyone else on your team has
died. Place claymores at each bomb location or nearby during this time as
well. When everyone is dead it is your job to go around and kick some ass,
make sure to be cold blooded and have ninja. Keep in mind in hardcore you
can usually kill 2 people before you get ricochet bullets, so you could
also try stealing a care package if you think it could get you 3 kills.

The Resourceful
If anyone knows a way to get this let me know. I don’t have a mic so I
can’t communicate with teammates to earn things.

The Survivor
You don’t need to be out of ammo per se, but just have your magazine
empty, making this easy to do as a witch/knife monkey.

Both Barrels
Unlike every other weapon in the game, the ranger has no ability to zoom,
so left trigger actually shoots the left barrel. Press both triggers while
facing an enemy to accomplish this.

Intimidation:
Omnicide
Easiest way is to use a chopper gunner or AC130 on Wasteland and hope the
other team is stupid.

Wargasm
Use 5-6-7 with predator missile for easiest result, get the missile then
get a double kill. Another method is to use one man army, do 5-6-7 and
when you get to 4, switch to a build with hardline, then get a single
kill, and use the predator missile to get one more kill afterwards.

The Bigger they are/The Harder They Fall
This is easiest done on Sabotage when the game is a lot longer. The top
player could vary from a traveling camper to a witch to a sniper. Keep the
name of the top person in mind, and when you see what they are playing
ass, counter it.

Crab Meat
Use a chopper gunner or AC130 on an open map in ground war. Easier if done
with danger close pro (especially for chopper gunner).

Ultimate Sacrifice
Easiest to be done in domination in ground war, as there are more clueless
people. Earn your nuke and then use it whenever your team is lower in
points. If you are winning, you may need to feed someone to earn them
killstreak rewards. More information on earning nukes in the killstreak
section.

The Denier
Same situation as the bigger they are challenge, but hope for the best.

Carpet Bomb/Red Carpet/Grim Reaper
Use danger close pro, and wait until the perfect opportunity. Best done on
domination in ground war with a UAV up.

No Secrets/Sunblock
Easiest to be done with hardline and suicides after earning them.

Afterburner/Air Superiority
Best done with hardline, has to be the exact same killstreak twice.

MG Master
This is easier to do in hardcore as people take fewer shots to kill. The
two best levels for this are Rundown (yes it has a machine gun) and
Skidrow (shoot at that glass door as well as the second floor of the
building). Remember that if you ever hit someone an X appears in the
middle of your reticule, and make sure to never overheat your machine gun.
UAVs and claymores can be very helpful, as well as having teammates near
you to protect you from witches/knife monkeys. I actually got this in
search and destroy on wasteland, but it was a combination of sheer luck
and dumb luck.

Slasher
Play as the witch/knife monkey, or just run around a random object, people
will chase you and then you can flank them.

Prestige:
Heads Up!
See Droppin Crates

Killstreak Rewards
These are just kill accumulations over all your prestiges, so use
killstreaks, get kills.

Knife Veteran/Last Stand Veteran/Stealth/Stun Veteran/Flashbang Veteran
These all reset when you prestige so choose some of them if you want to
work on them. I seem to complete knife veteran III before I reach level 30
usually, and stealth by level 45 if I am playing hardcore or search and
destroy.

Unmentioned Challenges:
These are challenges that don’t seem to be anywhere on the challenge lists
but I have gotten them blindly. If there are any more of these please let
me know, as it seems silly for us to have to find them by complete fluke.

Hijacker
This appears when you steal a certain amount of care packages from an
enemy, and it seems to reset when you prestige because I got hijacker II
twice. The easiest way to get this is in free for all, or in hardcore team
deathmatch, just kill a teammate if they are trying to grab it (it’s more
fun that way).

7 8 9
Why was 6 afraid of 7? Because seven ate nine! Hahahahaha. Anyway this is
accomplished by setting up a 7/8/9 killstreak and then earning it. I got
this one because I was trying to get helicopter inbound II, and the
easiest way is attack helicopter/emergency air drop/pavelow (keep in mind
pavelow kills do not count towards a kilstreak). I’m sure harrier and
stealth bomber work for this challenge too.

I Don’t Remember What This One Is Called
One day I realised that there was a clear button in the killstreaks, so I
pressed it. Surely enough you can actually play with no killstreak rewards
equipped. Then if you manage to get a 10 kill streak, you complete this
challenge, earning a 16 bit Mario in a green suit. By the way, does anyone
know how to have no perk 3 equipped, I’ve seen people without it in my
killcams.

Well that’s all, if anyone knows a good way to earn counter MVP or the
resourceful, please let me know. Have fun.
