Cheat: Rocket Launcher with Unlimited Ammo
Here's another example of "if you have the skill to unlock this, then you may not need it". We may not "need" a rocket launcher with unlimited ammo in Resident Evil, but it sure would be fun to have.
This unlockable has reappeared in many RE sequels, but it was first available in the original 1996 game. To get the unlimited ammo rocket launcher, all you have to do is beat the game with either Chris or Jill in under 3 hours. Let the credits roll and save your game. Then load the game and open the first chest to get the rocket launcher.
