Metal Gear Solid: Portable Ops Plus cheats & more for PSP (PSP)

Hints

Get Additional Special Weapons

When you unlock old snake, you get the M4-SOPMOD. When you unlock raiden, you get the mk23. You can get more of these weapons if you want. To get them, let either one of those characters die during a mission, and complete the mission. Eventually, you will find them as a random prisoner. When you find them, you will get another one of their special weapons.

Tech And Med Bonuses

If you get your tech level to 99, all weapons you find on the field will be higher Quality. If your medical level is 99, all medical supplies found on the field will be Large (they have L after them).

Extra Equipment

If you drag a solider around and then drop him you will get extra equipment. Depending on the solider type and the difficulty you could get something from medical kits to extra weapons.

How To Find Secret Items

On some missions, you can hear a faint ribbiting sound. You can follow it around, or use a Mine Detector (if available) to track the sound down. Once directly on top of the source, hold down the X button until you´re on the floor. An item should now have popped up from the ground. The items can range from armor, to hi-tech cloaking devices.
