The developers of Subnautica have announced the start of a new promotion, during which players are offered to get acquainted with the project for free:
You have crashed in a miraculous oceanic world where the only way is down. The oceans of Subnautica range from sun-drenched coral reefs to treacherous deep-sea fissures, lava fields, and bioluminescent underwater rivers. Manage your oxygen supply as you explore kelp forests, plateaus, reefs, and winding cave systems. The waters teem with life: some are helpful, many are dangerous.
The promotion with free access to Subnautica in Steam will last until April 6.
This year, they plan to release Subnautica 2 in "early access" format.
