Ultrakill Patch 17d3 Fixes Malicious Face Aiming and Cyber Grind Visuals
Ultrakill patch 17d3 introduces a proximity-based visual for the Cyber Grind death plane alongside multiple enemy and environment fixes. The update also resolves map geometry bugs in 5-1 and 8-1.
New patch 17d3 for Ultrakill addresses visual indicators, enemy AI behaviors, and performance hitches across multiple levels.
Visuals and Performance
The Cyber Grind now features a proximity-based visual indicator for the death plane. Additionally, the update reduces the hitch that occurs when entering the exterior area in level 8-1.
Enemy and Combat Fixes
Malicious Faces now aim at the player's center body instead of near their feet, with a modified system preventing them from hitting themselves. Gutterman line of sight is no longer blocked by rockets, and Sawed-On chainsaw durability now resets after 3 seconds when unequipped. Furthermore, killing a flying enemy with a Whiplashed core prevents the Whiplash from getting stuck in the air, and Size 2 fish are now catchable.
Environment and Level Corrections
Level 5-1 has a fixed navmesh in the cave that prevented Soldiers from spawning inside walls. The update also increases the height for Limbo door opening triggers and fixes radiant Stalkers, puppeted Mindflayers leaving beams behind after their Deathcatcher is destroyed, and active Providences affecting Virtue attack counts.
Why this patch matters
Patch 17d3 cleans up lingering AI bugs and performance hitches, smoothing out specific enemy interactions and level navigation.
