The story ties in with the second film, with the player controlling Niobe and Ghost, two of the supporting characters from the film. There was a big deal made at release about "expanding the universe" or some such bullshit, and there's a bunch of film clips with the original actors including some shot specifically for the game. So at least that is nice fanservice if you're still nuts for the franchise.
The game itself is a decidedly mediocre, bog-standard action game. EGM apparently gave it a particularly scathing review, saying it's "a complete mess, and that's the only thing complete about it." Ouch.
