Iconic Survival Game Is Free to Play on Steam Until April 6

Steam is offering Subnautica free to play until April 6 as part of a limited-time promotion.

Unknown Worlds Entertainment developed Subnautica, which launched in January 2018 after early access.

The game has about 175,000 Steam reviews and a 96.03% positive rating on Valve.

A franchise sale runs alongside the free weekend, discounting Subnautica and editions by 75%.

Subnautica 2 is slated for early access in 2026 amid development delays and related legal disputes.
