Krafton's creative studio Unknown Worlds will release the official sequel to the ocean survival series 'Subnautica' next month.

On May 1, Krafton-owned Unknown Worlds confirmed the early-access release date for 'Subnautica 2' as May 15 at 0000 and announced its pricing policy. The sales price for the South Korean market was set at 33,700 won.

Unknown Worlds also released a new cinematic trailer through major social media channels, including its official YouTube channel, along with confirming the release date.

Unknown Worlds CEO Ted Gill (테드 길) said, "On May 15, we are very happy to finally be able to present 'Subnautica 2' to players around the world." He added, "All of the developers are sincerely looking forward to completing the game together based on users' feedback during the early-access period."

Krafton head of publishing Jinhyung Lee (이진형) said, "The ocean survival experience shown by the Subnautica series has been expanded one step further in the new title through the co-op mode and a new alien planet."
