Mutants 2

Mutants 2 is no ordinary web-based game. The story is set at the end of the 29th century and everything has been demolished and technology is dead. You'll move around with the arrow keys, which isn't entirely linear so just be aware you'll be turning your body as you move. The mouse button shoots the mutant creatures you're trying to get away from. Your health meter will go down if you touch them. You can have up to five weapons on you, and can scroll through special items with the space bar. You will interact with NPCs and the game has checkpoints so if you die, all is not lost. Mutants 2 is a great little rpg/action game that will really get you hooked.
