Mutant Year Zero: Road to Eden is an upcoming video game adaptation of the 'Mutant' pen & paper RPG that has been kicking around since the 1980s. The whole premise is about as simple as it gets - Humanity has managed to nuke itself into oblivion, thus leaving the planet populated only by the titular mutants (deformed humans and animals alike), killer robots, and plenty of old-world ruins to scavenge for supplies.
As for the gameplay itself, Mutant Year Zero is a mixture of XCOM styled turn-based combat and real-time exploration, along with a bit of stealth thrown in for good measure. What this means is that you're able to freely roam across the world and explore it at your own pace, sneak around problems and scavenge for resources, and then when you inevitably mess up and raise 15 different alarms, transition to a rather familiar turn-based combat system.
Rather than continue to babble on, allow me to share with you the recently posted and rather lengthy developer preview. It'll give you a pretty good idea of just what Mutant Year Zero has to offer, as well as whether it's the sort of game you'd enjoy or not. Have a gander, it's quite a fun video:
If you prefer the written word, however, you should go and visit the official website to learn more. As for the release date, you might be interested to hear that Mutant Year Zero will be arriving this December 4th for PC, PS4 and Xbox One.
Oh, and just for good measure, I'll leave you with one of the earlier (but still quite lengthy) gameplay previews. Enjoy!
