ULTRAKILL is a fast-paced movement shooter made by Arsi "Hakita" Patala. You play as V1, a machine that is kept alive by blood. Fighting your way through hell, you encounter vicious foes...
The game features many different weapon combinations, sick tricks you can do, and basically has no skill ceiling. There are 4 (currently available) difficulties that affect enemy damage, speed, and other things, making it accessible to people not as experienced with shooters. For the challenge-seekers out there, a set of brutal bonus levels is available...
ULTRAKILL will release with 3 playable acts, with 2 currently available in early-access. It's 20 bucks or something like that on Steam, and if you're a shooter-enthusiast, you owe yourself to play it.
