Holy cow, MutEx zombies are insane. I got picked up and thrown through a wall, 2 display racks and another wall. It was like something out of a comic book lol. I think making them spawn in large packs was a bit much, they follow you through walls like it’s nothing and are at least as fast as runner. There’s no getting away from 6 of em at once, they just play with you like a beach ball.
Also…have you heard of secronom?
