Besides the awfully thought-out title, I'm proud of this game. The graphics are near non-existant, but it's not about that. It's about how fun the game is (and maybe how quick you push that MUTE button).
Your weapon evolves depending on how you use it (unfortunately with 29 weapons they're not all bug-free and some may just flat out suck). Hit F1 in game to view the instructions and notes. Oh, and there are more enemies as you level.
That's it! Have fun and enjoy my game! (Or die)
