While not a zombie game per se, the Doom series contains plenty of possessed humans with zombie-like attributes.
Despite what its detractors say (yes, it’s dark), Doom 3 is a damn scary game, and its zombies are some of the best (especially the one that jumps out from inside a bathroom stall).
31. Night of the Creeps (film)
This ’80s B-movie has everything: an alien invasion, an axe-wielding mental patient, zombies, young college students caught in the middle of it all... everything. It’s a bit spoof, a bit sincere, but mostly a great cult film and a tribute to the horror trendsetters that came before it. Unfortunately, it has yet to be released on DVD. Sadface.
