Gameloft, creator of great Android games you feel like you've seen before, is at it again with N.O.V.A. 3, the third (obviously) in the sci-fi FPS shooter series that follows
Master Chief Kal Wardin as he fights off the Covenant Volterite armada. The game's description touts an epic storyline and, frankly, we'd expect nothing less from Bungee Gameloft.
In all seriousness, despite the game's similarities to other major properties, Gameloft is well-known for making solid, enjoyable, if familiar, games. N.O.V.A. 3 also touts up to 12-player multiplayer modes, and unprecedented levels of storage space requirements (to the tune of 2GB). The game is available for $7 on the Play Store. Be sure you're willing to give it a shot, though. With that much data to be downloaded to play, you'll likely exceed the 15-minute return window long before you're able to play.
