A somewhat forgettable top-down zombie shooter but quite fun. Don't expect a story, characters or very involved quests. You just get enough reasons to explore around a few islands, populated by a variety of undead threats, some more fun than others.

I did run into a large number of glitches though. More than is reasonable.
- I crashed a lot until I unabled the Steam overlay, which seeemed to fix the issue, mostly.
- Controller is only vaguely supported and I had to use a third party app to map the keyboard controls to my controller
- "killed" undeads disappearing before I had the chance to loot them

Despite all this, I still recommend it because it's way more fun with a friend and as one of the very few couch co-op games remaining out there, it's worth getting on sale just for that.
