| Oct 25, 2026 | Update 0.3.2: health comes back and every zombie has a weakness This one comes from the first Early Access feedback thread and a long evening of my own play-testing. Thank you to everyone who wrote in. The early game was harder than I meant it to be, and a few things that looked like bugs in the moment turned out to be exactly that.The first ten wavesI went back to how the classic round-based zombie games handled their opening rounds and borrowed the shape.- O |

It is fixed, and while I was in there I went through the rest of the list.The shove- G on keyboard, click the right stick o |
