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.
Combat in ULTRAKILL rewards knowledge over reflexes. Understanding how each mechanic works — and how they interact — is what turns a struggling player into a dominant one. New here? Start with our beginner's guide for the basics.
Core Combat Mechanics
1. style ranking system
Every kill and action adds to your style meter from D to ULTRAKILL rank. Varied attacks score higher — using the same weapon repeatedly tanks your multiplier. Fresh Weapon bonuses trigger when swapping to unused weapons. Higher style ranks increase point gains and are required for P-ranking levels.
Why it matters: This is the foundation of all combat. Everything else builds on this.
2. blood healing
As a machine powered by blood, you heal by being splashed with enemy blood. Killing enemies at close range, punching them, or standing in blood pools restores health. This creates the core loop: aggression heals you, passivity kills you. Hard damage (gray health) can only be healed through blood.
Why it matters: The most underrated mechanic. Players who master this early have a massive advantage.
3. coin flipping
The Marksman Revolver's alt-fire tosses a coin. Any projectile that hits the coin auto-redirects to the nearest enemy's weak point. Shooting a coin with a railcannon or another revolver shot creates devastating trick shots. Coins can chain into other coins for multi-redirect kills.
Why it matters: Unlocks a new layer of gameplay depth once understood.
4. weapon swapping combos
Switching weapons mid-combat is essential for maintaining style rank and maximizing DPS. Core Eject Shotgun into swap-cancel lets you fire again immediately. Nailgun overheated magnets into shotgun blasts combo for massive damage. The weapon wheel has no swap cooldown.
Why it matters: The tactical edge that separates average players from advanced ones.
5. movement tech
Bunny hopping, slam jumps (ground pound for height), dash chaining, and whiplash grappling form the movement system. Slam jumping off enemy heads gives massive height. Rocket surfing (shooting a rocket at your feet mid-air) provides emergency mobility.
Why it matters: The endgame optimization mechanic. Small improvements here compound into massive gains.
Mechanic Synergies
Understanding how mechanics interact is where real optimization happens:
style ranking system + blood healing
Every kill and action adds to your style meter from D to ULTRAKILL rank. When combined with blood healing, as a machine powered by blood, you heal by being splashed with enemy blood. This combination is the core of every effective build.
coin flipping + weapon swapping combos
The Marksman Revolver's alt-fire tosses a coin. Paired with weapon swapping combos, switching weapons mid-combat is essential for maintaining style rank and maximizing dps. This is why the tier list favors builds that leverage both.
movement tech as a Multiplier
Bunny hopping, slam jumps (ground pound for height), dash chaining, and whiplash grappling form the movement system. Slam jumping off enemy heads gives massive height. Rocket surfing (shooting a rocket at your feet mid-air) provides emergency mobility. This system amplifies everything else — the better your movement tech optimization, the more your other mechanics pay off.

Advanced Combat Techniques
Damage Optimization
- Match your weapons to your role's stat priorities
- Exploit style ranking system for maximum damage windows
- Chain blood healing and coin flipping for combo damage
- Use weapon swapping combos to create openings
Survivability
- Learn enemy patterns before committing to attacks
- Core Eject swap-cancel: fire the shotgun, immediately switch weapons and switch back, fire again. This bypasses the pump animation and doubles your fire rate.
- Position using style ranking system to control spacing
- Save defensive options for guaranteed survival, not comfort
Boss Combat
Bosses test your understanding of every mechanic. See our boss guide for fight-specific strategies.
- Phase awareness — Most bosses change behavior at health thresholds
- Patience over aggression — One extra hit per opening beats dying to greed
- Build preparation — Swap gear and weapons for specific fights when needed
Common Combat Mistakes
- Button mashing — Committed attacks have recovery frames. Mashing locks you into animations.
- Ignoring blood healing — This mechanic exists for a reason. Players who use it take significantly less damage.
- Wrong weapons for the situation — Check our weapons guide for situational picks.
- Not learning from deaths — Every death teaches something. If you don't know why you died, you'll die the same way again.
- Overcommitting — Trading hits works in Limbo but will get you killed in Wrath.
