Gameloft is offering up two of its most popular games for free this weekend. Both N.O.V.A. 3 - Near Orbit Vanguard Alliance and Gangstar Rio: City of Saints can be downloaded at no cost for the first time ever. Originally released last year, N.O.V.A. 3 is a first person shooter with impressive graphics and a science fiction theme. Like many of Gameloft’s games, it includes a multiplayer mode that supports 12-player battles and voice chat to communicate with friends in real time. Our sister site TouchArcade has a review of both the single player portion of the game and the multiplayer component.
