Subnautica 2 hotfix 3 tones down predator aggression as the no-kill debate continues

Unknown Worlds dropped Subnautica 2's third hotfix since the early access launch on May 14, and it's squarely aimed at the game's loudest ongoing controversy: players can't kill predators, and a lot of them aren't happy about it. The studio isn't adding combat — but it is making predators less aggressive.

The specific changes: Hammerheads no longer attack unpiloted Tadpoles, though they can still take an interest in them. Marrowbreaches hit harder overall, but their attacks are spaced out so they come less frequently. Nibblers have a reduced perception range so players are harder for them to spot, they now circle longer before attacking, and their movement speed is down — but their overall damage is up and they're more sensitive to the Multitool. On the technical side, DLSS is upgraded to version 4.5, Interior Wall costs drop to a quarter of their previous price, and several crashes and a multiplayer rejoin bug are fixed.

The no-kill debate has been Subnautica 2's defining controversy since launch. Design lead Anthony Gallegos pushed back on the narrative in a recent MinnMax interview, saying Unknown Worlds never set out to make a "pacifism game" — that framing just isn't accurate. The studio has committed to adding predator mitigation tools over time, including creature flinches so players can actually feel their Multitool hits landing. The new "Increased sensitivity of the Nibblers to the Multitool" line in these patch notes looks like the first concrete step in that direction.

None of this has dented the game's commercial momentum. Subnautica 2 has sold 4 million copies and hit a peak of over 467,000 concurrent players on Steam — numbers Gallegos said genuinely surprised the team. Publisher Krafton has reportedly agreed to a $250 million earnout payment to the developers, a figure that was central to the high-profile legal dispute with Unknown Worlds' fired leadership.
