A great game, ahead of it's time. My only criticism would be there's not enough maps. Don't be put off by this, the game is plenty big. I'm just addicted! Love it, love it, love it.

In a nutshell, build up a community, choose and train your characters, secure strategic points on the map, all of it while keeping in check the plague hearts, disgusting pieces of flesh you gotta destroy to win the game.
This is not a simulation like Project Zomboid. It's not fast paced like any shooter coming to mind and it can be frustrating at some times... but hey, I always come back for more.
Depending on the difficulty you playing at, every move has to be calculated, every item can be useful and prioritizing your action become a necessity to not get destroy as it can escalate pretty quickly.
For 15$, give it a try

Such a great game that keeps getting updates to make it even better. LOVE it so much!
