Key changes from Hotfix 2 that directly affect how you play.
Hotfix 2 added more Silver nodes in the early game region. Standard Air Tank and Wiring Kit recipes both require Silver — this makes early progression significantly smoother.
See Silver in crafting guide →Hammerheads no longer follow your Tadpole's lights back to base. Deep exploration runs are safer — but still bring Dash or Chum Cloud for encounters.
See predator evasion builds →The infinite oxygen exploit while dying in a Tadpole is patched. Oxygen management matters again — consider Oxygen Control passive for long dives.
Update your loadout →No confirmed date yet. Unknown Worlds has confirmed expanded passive Biomod slots and creature balance changes are in progress for Update 1.1. Bookmark this page — it is updated the day each patch drops.
Hotfix 2 added more Silver resource nodes in the early game region and more Troilite nodes in the late game region, fixed Hammerhead behaviour so they no longer follow Tadpole lights back to base, patched two crash bugs (multiplayer connection loss and a late-game region crash), improved performance on Epic visual settings, and added a telemetry opt-out option.
In Early Access, Unknown Worlds has released hotfixes roughly every 3–5 days. Larger content updates are planned over the 2–3 year Early Access window. This page is updated within 24 hours of each patch releasing.
Update 1.1 is confirmed to include expanded passive Biomod slots, enabling players to equip multiple passives simultaneously for the first time. Further updates throughout Early Access will add new biomes, creatures, story content, and additional crafting systems.
