Cataclysm Dark days Ahead comes to mind.
A survival roguelike in a post apocalyptic setting. Main enemies are different kind of zombies, but you will also face robots, wildlife, mutated wildlife (bloody giant earthworms!) even fantasy creatures like the jabberwocky and if you want other survivors (who can be allies or your worst enemies)
Thing is all you can do is survive, there is no endgoal but surviving aslong as possible. You can create your own fortified home with barriers and spiked holes in the ground. Or create your own murder death automobile complete with spikes and turrets.
You can mutate yourselfe or augment yourselfe with bionics (but beware... most mutations have negative side effects)
Also the monsters arent your only enemies, you have to scavange for food and water, or start raising crops on your own.
You can learn and raise your skills from books you find and add new recipes to the massive crafting system, reaching from a rock in a sock to building your very own grenade launcher.
But again... this game is not winnable. In the end you will die one way or another.
What makes it different from project zomboid is the massive amount of content and diverse enemies you can encounter. However this all comes at a price ofcourse since like any roguelike it is either ASCI graphics or a tile based presentation.
