Moss Camouflage
When fighting The End, if you sneak up behind him when he is asleep and hold him up, he shakes down and will eventually give you the camouflage moss.

EZ Gun
Capture all 47 plants and animals to unlock the EZ gun in the game.

Killing Mini-Game
Once you get thrown in prison after being tortured save the game and turn off your PS2. The dialogue from the save chick will have something along the lines of, "I've got a bad feeling about saving here". Quit out, then load the game once more and you will end up playing some random killing game.

Metal Gear Acid
On the first floor of the Graniny Gorki Lab, interrogate the guard in the lobby three times and he will give you a code for the PSP game Metal Gear Acid. The code word is from Zone of the Enders II and it is JEHUTY.

Mosin Nagant
When you fight The End, beat him using only the MK22. You will get his Sniper Rifle, the Mosin Nagant.
