Recent verbatim reviews from Steam — separate from playze.io community reviews below.
I was waiting for a new concept of a 2D game and finally got this game right after it was released. The fact that you can mix different guns gives me the gambling feeling. If you are lucky you can survive for maaaaaaaaaaany rounds. There are few bugs that I exploit in the "araf" map, the zombies get stuck at the right end near the health regen, so if you guys wanna survive a bit more, you can use that area ':D. Generally speaking, it is fun and I really enjoyed playing it so far. I heard that coop is also coming soon, so I am looking forward to it and also for new maps as well.1 found this helpful
