Well, the prime objective is to shoot the people. Shoot them with your cursor. And when they're all dead, click the button for a fresh batch! It's more of a time wasting game then one that has an objective, but it's fun for a bit.
I have more at my site: www.beb.cjb.net
Oh, by the way: Police officers, Clowns, Mimes and the devil make neat appearances. :) Also: There are 6450 combinations possible, so you wont get bored that fast. I'll periodically upload with more people types. If you have any suggestions, feel free to Email me at alex@planethalflife.com
Enjoy.
