It's a zombie survival game. It's basically a sandbox you can play it alone or in multiplayer.
You might say that the graphics are outdated, but the gameplay is really fun! The game is on sale now as well it's about 10 pounds and normally it's around 15 pounds.
We are playing it on multiplayer server which @Jackal-Scot is managing on his vps.
It's quite challenging. You die quite easily.Just join our channel when we play and stream if you have questions.
