The hit strategy RPG, Mutant Year Zero, is getting its big expansion next month in the form of Seed of Evil. The expansion promises to bring a lot of new material, including an entirely new storyline complete with new, deadly enemies. There’s also a fresh character in the form of Big Khan and, oh buddy, this is a moose of a man (literally) who is not playing around.

Big Khan was briefly shown in the announcement trailer for Seed of Evil, but this trailer focuses exclusively on the character and includes some pretty weird live action segments that are…well, weird. Big Khan is a stalker who has been going exploring the deadly Zone solo. He finds himself wrapped up in the new conflict despite some reservations. His big attacks are Flame Puke and Ground Pound that hit multiple enemies at a time. You can check it out below.

Mutant Year Zero: Path to Eden is available now for PlayStation 4, Xbox One, and PC. The Seed of Evil expansion will release for all platforms on July 30th. It will coincide with a Deluxe Edition release that will see the base game and expansion in one package, and that version will also launch on the 30th, and bring the game to the Nintendo Switch.

The Bearded Ladies have announced a delay for the Deluxe Edition and Switch release of Mutant Year Zero: Road to Eden. That’s the bad news. The good news is that the game’s first expansion, Seed of Evil, has been announced and will be launching with the new release date for the Switch/physical version. Check out the reveal trailer below.

Seed of Evil will take place after the main story and features new maps like the Hall of Electric Coffins and Mausoleum of Suburbia, new enemies, ways to improve mutations, new gear, and a tough new adversary from the Zone. You also get a new playable mutant in Big Khan, a moose who can use his strength to score critical hits against foes. He’s also equipped with Ground Pound and Flame Puke for taking out crowds.

You’ll still be facing Zone Ghouls and Polis Bots, but they’ll be tougher than before. Still, it provides a good incentive to revisit Spear of Haven or the Sea Titans. Mutant Year Zero: Seed of Evil is out on July 30th, which is the new date for the Deluxe Edition and Switch version. Stay tuned for more details on the same in the coming weeks.
