The campaign I admit is too short. But the mutliplayer kept me coming for a couple weeks, worth the $ definately IMO. Keep in mind I played on a ipod 4rth gen so I had the retina graphics and the controls were easy to reach. It's easily the best fps in the market, the graphics are good, their are a large variety of guns for an Iphone game and there are 4 unique multiplayer maps. The guns are balanced and the server is wayyyyyy better tehn the Nova one. Get it Elly, I doubt you'd regret it.
