okay, since i dont know how to post cheats or easter eggs im posting here

while using the mk2 or mk3 look at snake's hands, he is using a ps3 controller

in the cutscene/mission briefing after the level where you meet drebin press square (or is it triangle?) to change a screen into mk2 view then press L2 to go into mk2 mode you adventure around the plane now go behind the computer closest to the stairs there is the camera it has normal mode and controller 2 mode ,after that go upstairs grab everything and wait sunny should come up and open a box look near the box a PS3 and PSP and some noodles!

if you help some militias equip a healing item and press triangle next to them you give it to them and they will give you something cool like rpg ammo or a song:)

if there is something you find feel free to post it here

*my brother beat it twice but we still havnt got everything because you have to befriend the militias to get some things)
