Metal Gear Solid 3 Snake Eater added a camouflage element to the series. Along with that new element came dozens of collectibles that you'll want to find. Some of these great Metal Gear Solid 3 cheats will impress anyone that sees them:
The Snow face paint is in Bolshaya Past base, in a fox hole of the left of the middle building. The Water camo can also be found in this same area.
You’ll find the Desert face paint in the Ponizovje warehouse.
You can find the Oyama face paint in the air duct of the Graniny Gorky lab.
Look behind the building in Rassvet during the Snake Eater mission to find the Zombie face paint.
The Kabuki face paint is located in Tikhogornyj, at the bottom of the pool before the waterfall.
The Rain Drop camo is under the rope bridge in Dremuchij North.
The Splitter camo and the Chocolate Chip camo are both in Bolshaya Past south.
The Snow camo can be found right before the Pain in Peschera Cave.
The Ga-Ko camo is in Chyornyj Prud, underneath the water.

The Officer uniform can be stolen from Raikov.
You can get the Sneaking Suit uniform in the Groznyj Grad weapons lab, in the locker with the red stripe on the front.
The Fly camo is in the third bathroom stall on the second floor of Granin’s building. The door is locked so you’ll have to break it down.
Endure the Sorrow’s entire river to get the Spirit camo.
Complete every level in Snake vs. Monkeys to get the Monkey mask.
To get the Water face paint, after you fight the Fear, return to the beginning of Ponizovje South.
There are two ways to get the Infinity face paint. Either beat the game with the Foxhound rank, or complete a second, more complicated method. Catch a live Tsuchinoko before your torture scene. Afterward, once your weapons are returned to you, go back and capture it again. Finish the game with it alive.
Finally, to get the Santa, Mummy, and Grenade camouflages, you need to download them onto a memory card using a network adapter.
