Hunter the reckoning you fight agains a huge amount of enemies, zombies, gargoiles, were wolves, vampires, etc. anything super natural. Since the amount of zombies is huge maybe it can stay.
Siren, the enemies are killed by a fog and then they return to kill you but they don't eat you. But they are 50% zombies.
Blood and nightmare creatures have zombies on them, but not as main enemy.
Splatterhouse;i say this one is out. you fight agains demons and monsters created by Dr. West. Still a really good game though.
Aparently Amy has some enemies that look zombie-ish.
Brawl Busters has a zombie mode (like CoD, but is a brawler).
The DLC for borderlands "the zombie island of Dr. Zed" is listed twice.
Clutch and Carmaggedon have zombies on them just to get smashed, both are basically racing games (i think clutch is a bit more open world need for speed most anted style).
Zombie hunters is Onechambara but that's the name for the PS2 version outside of Japan.
Country justice: Revenge of the rednecks... if you like to laugh at horrible games search a gameplay for this one.
Zombies and Pterodactyls... what? I think this one only has zombies on the title of the game.
Minecraft... really? Minecraft? Creepers are the biggest enemy there, you have zombies for lunch there.
They Hunger series are MODs for half life 1, and as far as i know they don't have stand alone versions.
We have to discuss if the enemies on dead space and Area 51 games can be considered zombies.
I think your list misses Night slashers (arcade game)

This are some quick checks (the games that have ZOMBIE on it i leave them alone for now) but i'll like to do a one by one research of every game.
