The old story, recorded dialogue with Dennis Quaid and Michael Ironside included, has been scrapped. Gone is the tragic war veteran who lost his daughter and replacing him is you, the player. Taking on a classic RPG style of unnamed protagonist, you're just a player in the war game, so to speak. If you were a silent protagonist, that'd be awesome, but unlikely. Regardless, you travel to an alternate timeline and take on an army of warriors protecting the man who changed the flow of time to make himself leader of all things gritty, dark, and somber.
A new time-control scheme lies in your suit, dubbed S.S.A.M. and given a female persona. One button controls the ability to stop, slow, or rewind time, depending on which would be most beneficial in a given situation. Using these in the levels would be nice, but the first four completed levels were completely scrapped, replaced by gigantic new ones, each with a specific purpose to advance the story. There's plenty more to discuss, like the enhanced AI, puzzle-solving opportunities and other gameplay gimmicks, but we'll stop here and let you check the rest out on your own. Shooters have to try harder to differentiate themselves from one another and this game is trying harder than most.
