The world of Subnautica 2 is pretty hostile; everything from the local fauna to the temperature can cause you injury, and if you want to survive on this alien planet, you'll need to adapt. One of the main ways you can do this is by finding and curing large, strange plants called Angel Combs and combining your DNA with theirs. There are a few ways to stay safe in Subnautica 2: you can construct a Tadpole to give yourself a bit more mobility and a bit of extra protection, and you can find blueprints to fabricate better and more efficient equipment. Angel Combs are a core measure of your progress, though, giving you deeper access to the ocean, and here's where you can find them.
