UnknownElementX is right. The idea of conquering the other faction in this way already exist in a game called galcon. ( http://www.pygame.org/project/340/ )
There is a very similar game on YoYoGames called grapnel as well. The creator there is called 'ArchMageOmega', so it could be the same guy, but this game could be copied as well. Here's the link:

(This is not a flash game but a game maker game.)
I love the music, but there is one issue for me: It's too slow! Maybe it should be possible to shoot your ball while moving, because more friction seems somehow like a bad idea to me. Anyway, after newsninja's tip I enjoyed the game!
At first I was like: Awesome, arcade style driving around and killing zombies! And it's full of clichés and stuff! But it wasn't that awesome after all.
Nice game, but I don't like the fact that blue elephants are coming out of a detonated egg. When you release an update, make an option to turn this off!
Two lines, how hard can it be?
