It seems clear that the only reason Terminator: Salvation exists is to cash on on the popularity of the movie with which it shares its name. It doesn't push any borders, nor does it introduce anything new to the third-person shooter formula. The cover and flank mechanic, which feels pilfered from the Gears of War games, is competent but unexceptional, having already been implemented in plenty of other shooters. That verdict applies to just about everything in the game, whether you're manning a turret in a jeep or fighting a big boss like a Hunter-Killer warbird; it's all been capably executed, but shows little evidence of originality or flair.
Post-Armageddon Los Angeles looks great, as do the beautifully rendered, action-packed cut scenes, but the atmosphere suffers from uninspired, lifeless dialogue (Christian Bale, Helena Bonham Carter, and many of the film's other major actors are, unfortunately, absent from the game's cast). Too bad, since a strong story might have made players want to experience it a second time in co-op mode, which has the potential to double the length of this very brief adventure. Best leave this one to die-hard Terminator fans and look to longer more innovative interactive experiences.
