Alien Frenzy by Fireshark Studios
You are the last soldier alive stranded at a far outpost and the aliens have found a way in. Stay alive as long as you can in this fun and action paced survival shooter by leveraging the right buffs and special abilities. We aimed for a game play that is best described as a cross between Alien Swarm, Left 4 Dead, and Defense of the Ancients. The game is free in the iTunes App Store so no promotion code will be necessary for you to try the game.
