Unknown Worlds‘ Subnautica 2 has sold 2 million copies in just 12 hours after entering Early Access on May 14, per PCGamesN – doubling the milestone the studio announced just one hour into launch. At its peak, the game pulled in 651,000 concurrent players across Steam, Epic Games Store, and Xbox, with Steam alone hitting 467,582 simultaneous players according to SteamDB data. For context, that peak puts Subnautica 2 comfortably among the biggest survival game launches the platform has ever seen, which is a genuinely unusual thing for a Steam Early Access day to be.
At $30 a copy, 2 million sales translates to roughly $60 million in gross revenue before platform cuts – and that’s in under half a day. We covered the jaw-dropping 1 million copies in under two hours milestone earlier, but the pace didn’t slow – it just kept building. For comparison, Pragmata – which hit 2 million copies sold in 16 days and was widely celebrated for it – now looks like it had the luxury of time. The 93% positive rating on Steam suggests the momentum isn’t purely hype-driven, either.
Honestly, the number that really matters here isn’t the one on the box – it’s the one in the legal filing. Unknown Worlds‘ split from publisher Krafton came with a reported $250 million earnout clause tied to Subnautica 2‘s commercial performance, and 2 million copies in 12 hours is exactly the kind of opening that makes that dispute very interesting, very fast. As we noted at launch, the game’s commercial trajectory is inseparable from that legal backdrop – every sales update is, in effect, evidence in an ongoing argument about who gets paid and how much.
What to watch now is whether Subnautica 2‘s momentum holds through its first major content update, and how the Krafton earnout situation develops as those sales figures become harder to argue with. Are you already in the water, or waiting for more content to drop before committing? And does the Krafton context change how you see this milestone?
