State of Decay is a zombie survival game that was developed by Undead Labs who did a great job. Are you looking for a game that you have to go find materials then build up your camp then take quests to progress further into the story? Then State of decay is the game for you. There are skills that you have to level like cardio kind of like Escape from Tarkov but it’s not that hard like Escape from Tarkov.
I couldn’t recommend this game enough 10/10 but I think you should buy State of Decay 2 first unless you want to play the older one which doesn’t have that many things that you can do, unlike the second game. Sadly they don’t have multiplayer but the second game does and in my opinion, it’s not the best because from my experience the owner of the lobby gets to do all of the quests the other players can but they don’t progress. I will do a review of the second game in a couple of weeks. your base/camp can get attack by a horde of zombies that can hurt the population or can just flat out make you lose the game.
