Set in the near future, it's about a massive underground office block that has been sealed off due to contamination from one of its labs. Lead by a guy called One (Salmon), a team heads in to assess the situation. We've got two amnesiac employees (Jovovich and Purefoy), a handful of feisty soldiers (Rodrigues, Crewes, Aleardi, etc) and a captured corporate spy (Mabius). Soon they realise that the leaked virus causes dead office workers to re-emerge as characters from Night of the Living Dead. And if that isn't enough, the evil computer system is trying to stop them as well.

The relentless action plays exactly like a video game, with levels the character must progress through--fighting increasingly brutal villains before moving onto the next environment. And they lose a "life" every time a team member gets infected, eaten, sliced to ribbons by laser beam, whatever. This progressive structure and a decent cast are all that makes the film watchable. Anderson simply hasn't a clue about creating cinematic suspense; he obviously thinks that screeching chords of music are terrifying. But he never shows us the threat, so we have nothing to be remotely afraid of. You find yourself bracing for the next deafening shriek, which comes right on schedule. Yawn!
