Game's on Early Access, with a randomized survival mode currently and its campaign mode coming next year. It's quite polished and solid already, and it's one of the few games I've played that makes zombies truly feel like a threat to fear rather than fodder (others being Death Road to Canada, Project Zomboid, and State of Decay). In this game, if just one zombie breaks through your defenses, all might be lost.
I don't typically like base building in RTSs, but it's really satisfying here, even in these early stages. Needing to balance defenses, resources, military while preparing for the inevitable crush of undead is quite satisfying

They Are Billions is a strategy game in a distant future about building and managing human colonies after a zombie apocalypse destroyed almost all of human kind. Now there are only a few thousand humans left alive that must struggle to survive under the threat of the infection. Billions of infected roam around the world in massive swarms seeking the last living human colonies.
