Awesome game. Suggestions: I've played for a while and only experienced one freeze, but yeah, fix that. Then make tackle and shoot two different buttons, like others have said. And fix the goalies please! They're basically useless.
Too unbalanced towards the USS and the dish--like others say, upgrade their firing costs a lot. Otherwise it's just two people shooting nukes at each other.
It was fine but man did I hate the plot and writing. Enjoyed the graphics (a sniper game without stick men!), but wish it hadn't just been all men walking around.
