Metal Gear Solid 3: Subsistence cheats for ps2

Hint: Acquire the Sneaking Camo

After you take out the Raiden look-alike, you’ll be tortured. Escape, then go back to the Groznyj Weapons Lab (the second time). Go to the locker where Raiden’s bodysuit was. You’ll find the Sneaking Camo in there instead. The Sneaking Camo allows you to sustain half damage!

Unlock Stealth Camo
Shoot all 64 Kerotan frogs. There is one in every level and using the GA-KO camouflage can help you find them easily. The GA-KO will give a faint Kerotan sound (Wakka-Wakka) and it gets progressively louder when you are closer to a frog; you can use the Directional Microphone to hear it even more easily.

To get the GA-KO camouflage, find some shallow water with a Chaff Grenade box in Chyornyj Prud. The camo item is next to the grenade pick-up.

Unlock Moss Camouflage
To earn the Moss camouflage (makes you 100% hidden in mossy and grassy areas) you must sneak up to, and hold up (mug) The End (the old guy) and don't tranquilize him (or let him die by accelerating your system clock).

A good way in getting the camouflage and The End's tranquilizer sniper rifle is to hold him up first, then tranquilizing him. The Spirit camouflage lets you get close to The End without being detected; to get the Spirit camo, clear the level with The Sorrow in a previous game.
Hint: FU To The Fear
When you fight the Fear, you can kill him easily. When you began the fight, there is a tree that you can climb on the Northwest of the map. Remember, its the farthest one with the vines to climb, this position gives you cover from the right side, the Fear will shoot his arrows at you from that direction, but a tree will block all of his shots. The Fear will ONLY jump on two trees, the one from your right side and one in front of you. For some reason, he just sits still for a while and does not attack when he gets to the tree in front of you. it might not work all the time, but it worked for me. You can also try the tree on the right side when you right side when you begin, the Northeastern tree.
