Hints

BFG-9000

The Bio Force Gun (BFG-9000), is one of the most advanced weapons known to the UAC. To get it, go on Delta Labs 2B on Veteran and find the Martian Buddy Locker and type in 0508. Also, when your in the portal room back to Delta Labs, go around the portal and you'll find an opening. Go passed it and up the stairway. Once you reach the end, you'll see some plasma cells and the BFG-9000.


Sticky Laptop

On the level Monorail Skybridge Sector 2 when you go inside a small room with a Soda Machine you will see a laptop on the table and if you shoot with a shotgun, it will go flying and stick to the glass wall.


Saving Ammo

After you get the chainsaw, use it on zombies and mosters that don't shoot at you. This will save you tons of ammo for later levels.


Using Your PDA Properly

Be sure to check your PDA often for E-mail. E- mail on your personal PDA or the PDA of someone else for Access codes, Updates, and useful information. I spent hours on the monorail access code trying to guess it because i forgot to check my PDA.
