Contract J.A.C.K. is billed as a prequel to the super-excellent shooter No One Lives Forever 2. What we really have here is a modest set of stand-alone expansion levels for NOLF 2. It uses the same game engine, graphics and features a new main character but really not much effort was put into the story or game-play. While there are a handful of funny character interactions, mostly this is a linear, run-and-gun shooter. Don't play this one expecting any of the dialogue or varied game-play that made NOLF 1+2 two of the best PC games ever created. J.A.C.K. is okay, I guess, but would rather play NOLF 3 instead.
