Mullet Mad Jack has a new update and game mode. In the new Boss Rush mode, you have to beat Mullet Mad Jack’s toughest enemies in record time. Make it to the end, and you’ll encounter the shooter’s hardest opponent yet: one of the iconic villains from Ultrakill itself. A loving homage to the classic era of Quake and Unreal Tournament, complete with blocky, polygonal visuals and gallons of gore, if you’ve beaten Ultrakill in the past and you’re ready for a fresh fight, this is the ideal crossover.
