Killer Wolverine writes: First-person shooters; for years, they have dominated the console market with stellar titles like Halo, Unreal Tournament, Battlefield and Killzone. Now, they are making their appearance on the XBLA and PSN. While they aren't as abundant as their console big brothers, they are slowly but surely making a name for themselves as downloadable titles. CellFactor: Psychokinetic Wars from Ubisoft is one of the first of these games to ever blur the line between a downloadable game, and a retail one. If you are familiar with Unreal Tournament, you will feel right at home with this title. 8.5/10
