Hrmm.. It's a 'second fire' because lot's of people gave you advice to 'aim smaller' and do a nice small game, rather than trying to make a massive team, and you seemed to not really have taken notice of this advice... It is however a cool idea, and one that's been tried before, go check out the Community FPS in the WIP section of the forums.
Also, I'm not sure whether this would count as a Team Request, and I think they're pretty much banned on here [Unless you really do put the effort into the stuff you already have AND the post], so if this does get locked, I wouldn't put my money on the reason being because you asked...
Soo.. Aim smaller! Make a Pong game, or if that's too simple, another fun Arcade game.
