ULTRAKILL is a retro fps made by Arsi "Hakita" Patala and published by New Blood games, the premise of this game is:

"Mankind is dead

Blood is fuel

Hell is full"

You're V1, a machine that runs on blood, and since on earth, ever since the erradication of humanity, blood is running out, you decide to go through the nine layers of hell in order to get the necessary blood needed to keep functioning.

This ties to gameplay, as the only way to regain health, is to damage enemies (which bleed on a small radius) at point blank, this only works on fresh blood, so going to a nearby corpse and damaging it further won't count.

This game has been praised for being generally faster than doom, and for having aesthetics resembling those of the ps1, the reviews on the steam page are overwhelmingly positive, even when the game is on early acess.

Currently this game offers the first four layers of hell (and a prelude) and a wave mode called cybergrind, which is fully customizable (as in how the arena looks, gameplay modifiers coming soon).

This would be a good addition because due to having many movement options, the option of highlights would be good for sharing a self's skill in social media.
