Gameloft has released the first official gameplay footage of N.O.V.A. 3, aka Near Orbit Vanguard Alliance 3, a FPS futuristic sci-fi shooter. The actual gameplay in the video is less than 40 seconds, but you get a sense of the San Francisco setting.
Still no word on whether there will be a Mac port, following in the footsteps of N.O.V.A. 2.
