kiki1, I may be the only guy here saying this, but kudos. kudos for at least trying to make something. Of course agree with what other people said and this isn't technically a game if you look up what a game is defined as, but you know what I am 14 and I took a whack at the Unity 3 engine... I couldn't even figure out how to make my terrain. ( I couldn't find terrain editor) so I decided to just use UDK to mess around and make little arena maps. So you know, I gave up. But you didn't, and congrats on that.
A few more guns, game modes, grenades, Vehicles, and a little bit more polished graphics, This game could, in my opinion, very well compete with many console shooters out there.
