Ultrakill is a hyper-violent, retro-inspired first-person shooter that has spawned a massive wave of internet memes due to its high-octane gameplay and dramatic lore. The game's intro—'MANKIND IS DEAD. BLOOD IS FUEL. HELL IS FULL.'—became an instant classic, often parodied to describe different mundane or intense situations. Characters like the protagonist V1 and the antagonist Gabriel, the Judge of Hell, are frequently featured in memes ranging from deep-fried irony to high-effort animations. Usage typically revolves around the game's steep difficulty, the 'stylish' ranking system, and the absurdly powerful coin-parrying mechanic, making it a favorite among the gaming community for both shitposting and celebrating skill.
