I can't remember the name of a game I tried MobyGames but I didn't find it if someone can help me I'll try to describe it
Ok so it's a game in third person with zombies you have a church as a base and there's a dlc I think where your base is a military base, when you die you take the control of another person, there are cars and weapons you can find all over the map also you can upgrade your base and sometimes you can find survivors and if you save them they join your base I can't remember more details I hope you can help me

State of Decay

The original version (Steam key) is still available on Amazon I think

Parts of this description reminds me of Stubbs the Zombie, but then also maybe Omikron, because you can takeover dead people. But I doubt if either is your game.

Sorry.

If it wasn't for the third person requirement, it could have been Cataclysm: Dark Days Ahead.
