Boom, Headshot :)
That is exactly what you did with this game :) it rulz, and i'll tell you why.
1) good weapon selection. and not just the basics, either. its a FLAME shotgun or a BIO uzi. and they all do stuff too, not just make the weps sound cool.
2) character customization. i love custom stuff. and you have 20 choices for all 3 parts - thats 8,000 different possible characters.
3) Deathmatch story. never seen a story done without actual levels, but you knocked it outta the park.
4) its just plain fun.
5)i can't even think of anything bad about it. maybe a lack of modes, but who needs em? deathmatch is king anyhow. i couldnt picture CTF on this. not ever.
Nice job, keep it up.
