Time Attack Mode, Snake in a Tuxedo, and More

Bandana and Demo Theater Roll A:
Don't submit to Ocelot's torture and instead finish the game. After the end credits, a screen appears announcing your prize: a Bandana that gives you unlimited ammo. Save the game data, start a new game using that data, and you'll find the Bandana in your item inventory. To access the Demo Theater Roll A, Finish the game as you did above. At the title screen, enter the Special Menu and you should find a new option, Demo Theater. Enter this new option and you'll find Roll A, which lets you watch all the cinemas in the game's "A" scenario.

Stealth Camouflage and Demo Theater Roll B:
This time, submit to Ocelot's torture and finish the game. After the end credits, a screen appears announcing your prize: Stealth Camouflage. This item keeps you cloaked from all enemies in the game except boss characters. Save the game data, start a new game using that data, and you'll find the Stealth Camouflage in your item inventory. To access the Demo Theater Roll B, finish the game as listed above. At the title screen, enter the Special Menu, and you should find a new option, Demo Theater. Enter this new option, and you'll find Roll B, which lets you watch all the cinemas in the game's "B" scenario.

Snake in a Tuxedo and Red Cyborg Ninja:
Play through the game using the saved data from each game. Don't submit to Ocelot's torture during the first game, but submit during the second game. Also, don't use the Bandana or the Stealth Camouflage during either game or the trick won't work. After you finish the second game, start a third game with the saved date from the second game. When the game begins, Snake will be dressed in a tuxedo, a la James Bond-- and when you encounter the Cyborg Ninja, his blue armor will now be red and vice versa.

Time Attack Mode:
Enter the VR Training mode and successfully complete Training Mode. When you re-enter VR Training mode, you'll find a new option, Time Attack Mode.

Gun Shooting Mode:
Enter the VR Training mode and successfully complete Time Attack Mode (see the above cheat for information on how to access this mode). When you re-enter VR Training mode, you'll find a new option, Gun Shooting Mode.
