We blasted our way through a full five-map campaign we'd seen already, which culminates in a rooftop defense against a pair of ultra-powerful tank zombies. The game's graphics definitely look cleaner than before, and the character animations in particular caught our attention. For instance, human characters low on health will don frightened expressions on their faces, to the point where you might even feel slightly sorry for them as they fire wildly into the ever advancing horde. With shotgun and bullets blasts it's also possible to stop a zombie short in its tracks, sending it crumbling to the floor and giving you a more satisfying sense of a successful kill.

In addition to firing weapons, there's a melee swipe when you've got a weapon drawn, something that's absolutely essential in close quarters. For instance, if a boomer barfs on you, as they tend to do, a sizable group of zombies will come screaming from the darkness to tear apart your face. Amidst the chaos of flailing undead limbs, you'll need the melee swipe to disable those close to you and knock them back to open up some breathing room. It's also a valuable attack while fighting in cramped corridors, since friendly fire is always on and, generally, you want to avoid embedding bullets in the back of teammates' necks.
