Crispy Gamer: More than a downloadable update, Left 4 Dead 2 is an honest-to-God sequel to last year's smash-hit co-op shooter. That means four new characters fighting for survival through new co-op and Versus campaigns. New weapons, new zombies, new everything! Did I mention that Left 4 Dead 2 is all-new?
The Verdict: Only the brain-dead would consider a boycott.
