MacWorld: With the release of the original N.O.V.A., Gameloft drew a well-defined line in the sand on what a first-person shooter should look (and feel) like on an iOS device. Since then, other games, like id’s Rage, and even Chair Entertainment’s Infinity Blade, have redefined our expectations in terms of graphical capabilities and gameplay complexity.
STP - "As part of our 50 Best Game Series on iOS, we’ve covered Modern Combat and Dungeon Hunter, both Gameloft knock-offs of popular console and PC franchises. Gameloft’s sincere flattery extends to the Halo series, which they have reverse-engineered like a piece of alien technology, bringing their own epic sci-fi first-person shooter series to mobile devices."
The Quality Index champions the best Gameloft titles available on iPhone.
NOVA 2 from Gameloft is one of the most impressive games that came out for the iPhone. NOVA stands for Near Orbit Vanguard alliance. If you've played games like Halo, Portal or Crysis then you'd be very much at home with NOVA 2.
