The Fallen is a great game off of ST: DS9. It uses the Unreal engine for graphics and looks awesome, with some enhancements to make it look cooler. But unlike Unreal, this is a third person game, not first. But they make it work great with the same controls as Unreal! You can play as 3 characters telling a interwoven story. This game is both fun and challenging with some awesome Star Trek action. It's like you're playing an episode. The only thing is Sisko's voice isn't his from the show, hard to get used to. But the game is still really cool, and you can explore most of DS9! (And the Defiant!)
