CDDA is a zombie survival game with a heavy focus on realism in it’s mechanics. The controls can be intimidating if you’ve never played a game like this before. You might need a cheat sheet open on the second monitor or maybe your phone, but I think it’s worth the effort getting the hang of it.
CDDA is available for Windows, Linux, OSX, and Android.
If you’ve ever wanted to drive a car in a turn based game, while running over zombies, while having a realistic damage model, while trying to figure out what the fuck you pressed that made a screen pop up that you can’t easily close… This is the game for you.
Oh there’s also more mods than you’ll ever experience.
