ULTRAKILL is a retro-styled FPS inspired by Quake, Devil May Cry, and classic arcade shooters. Set in the layers of Hell, you play as a machine fueled by blood, meaning aggressive play literally heals you. The style ranking system (D through ULTRAKILL) rewards varied combat, weapon swapping, and creative kills. Every weapon has multiple variants with distinct alt-fires, and the coin-flipping mechanic lets you redirect shots for trick kills. Currently in Early Access through Act 2, it's already considered one of the best boomer shooters ever made.
ULTRAKILL features distinct areas with increasing difficulty. This guide covers every major location in progression order — what to do, what to get, and when to move on. For the step-by-step path, see our walkthrough.
