Contra III: The Alien Wars/Codes and passwords

Each version of the game has unique codes and passwords.

Note: The Konami Code does not work in any version of this game.

Super Nintendo

These are codes for the 1992 game known as

• Contra III: The Alien Wars
• Contra Spirits
• Super Probotector: Alien Rebels

Infinite lives

The Attack Ship in Stage 3 spawns infinite enemies, which can be exploited for infinite points. Equip the machine gun and move as far to the left as possible so you can fire to the right. Enemies will keep coming and get killed by your bullets, racking up points, which translates into lives (up to 29). If you get bored you can tape the fire button down (or use a binder clip) and go do something else.
