About Ultrakill

ULTRAKILL is a first-person shooter built for speed. You're a machine in Hell, and the central mechanic is that blood is health — you heal by being close to enemies as they die, so hanging back defensively actively kills you. Combined with a dash, a slide and no reloading, it produces combat that never lets you stop moving.

This page runs the free Prelude — the opening chapters that developer Arsi 'Hakita' Patala released as a standalone demo — as a web port. The full game is a paid release on Steam, and it's one of the most acclaimed shooters of recent years.

1. Fight through the level's arenas against waves of enemies.
2. Stay close to enemies as they die — blood restores your health.
3. Dash and slide constantly; standing still is fatal.
4. Switch weapons for the situation; there's no reloading.
5. Each level is scored on style, speed and kills.

Ultrakill tips

• Aggression is the defensive option. Backing away means you never heal.
• The dash has invincibility frames — use it through attacks, not away from them.
• Sliding preserves momentum; chain slides and jumps to keep speed.
• Vary your weapons for a higher style rank; repeating one kill type scores less.
