Ultrakill Fraud Hotfix #2 Adds Air Control Tech and Ridable Guttertank Rockets
Ultrakill receives a massive overhaul with Fraud Hotfix #2, introducing new Wind state air control, reworked rocket-riding mechanics, and extensive Cyber Grind balance adjustments. The update also tweaks weapon behaviors, adjusts enemy stats, and fixes a mountain of level out-of-bounds bugs.
Fraud Hotfix #2 lands for Ultrakill, bringing sweeping changes to movement mechanics, weapon interactions, and enemy behavior. Alongside quality-of-life additions like a reduce HUD motion toggle, the patch refines speedrun techniques and balances high-difficulty encounters.
Movement and Air Control Tech
Players gain access to new "Wind state" tech for greater air control, activated through a non-damaging rocket jump, a walljump while diving, a dash extension, or by dashing into an enemy step. Dash Extension speedrun tech is officially restored, "duckboost" consistency is improved, and "SSJ" speedrun tech is now framerate independent and prioritized over dash jumps. Additionally, a new "reduce HUD motion" option disables weapon and HUD swaying with velocity.
Weapon Reworks and Combat Adjustments
Magnets now function across portals, and players can mount rockets by holding down the jump button while pulling a rocket with the Whiplash. Guttertank rockets pulled from below are now rideable just like standard rockets, and riding a rocket into an enemy always triggers a red explosion. The Core Eject Shotgun's alt fire can now be fired immediately after drawing the weapon and charged during primary fire, while ejected cores now feature a tracking trail. The Knuckleblaster's explosion wave pushes player projectiles in the aiming direction, and the Sawed-On Shotgun no longer resets chainsaw durability when swapping weapons mid-saw.
Enemy Adjustments and Balance
Destroying an Idol or Deathcatcher now registers as a kill, updating level rank requirements accordingly. Non-boss Swordsmachine phase change knockdown duration is reduced, and non-boss Mirror Reaper health drops from 80 to 70. Mirror Reaper vertical swings no longer hit sliding players, and its hands can now be parried with the Feedbacker or instantly broken with a Knuckleblaster punch. Radiance speed bonuses are lowered for the Sisyphean Insurrectionist, Hideous Mass, and Providence.
Cyber Grind Adjustments
"Uncommon" enemy spawns can now utilize up to half the total point count per wave. The Cyber Grind limits Mirror Reapers to a maximum of one per wave, which now only spawn in when the player reaches the halfway mark. Deathcatchers now activate 33% of the way through a wave and remain caged until the 75% threshold.
Level and Bug Fixes
Level time leaderboards are now scrollable, defaulting to and highlighting the user's personal time. Numerous out-of-bounds exploits and collision errors have been resolved across multiple levels, including fixes for the 8-3 Dimensional Cave, 0-1 and 0-2 boundaries, and 5-2 rain visual issues.
Why this patch matters
Fraud Hotfix #2 shakes up Ultrakill's mechanical meta by formalizing advanced movement options, tightening weapon utility, and smoothing out rough edges in late-game arenas.
