Unknown Worlds Entertainment has made quite a splash, with Subnautica 2 vaulting straight to the number one spot on Steam’s global top sellers list the moment pre-sales kicked off.

As the latest entry in this deep-sea survival adventure series, Subnautica 2 shifts to the Unreal engine for a visual upgrade and, finally, officially supports the four-player multiplayer that was previously locked behind community mods. Pre-sales and pre-downloads officially went live at midnight on the 12th, propelling it to the top of the charts.

Before the pre-sales, the developers hosted a live showcase on the 9th, pulling back the curtain on the game's evolution and development secrets. They even took the controls themselves to demonstrate the new 'Tadpole' vehicle and the expanded base-building customisation options.

The anticipation was palpable, with the game hitting 5 million Steam wishlists by the 11th. To celebrate this milestone, early buyers will receive a blueprint for a Reaper Leviathan statue to spruce up their underwater abodes.

Subnautica 2 is set to hit Early Access on the 15th. The team expects to spend roughly two years in this phase, promising a steady stream of updates that will flesh out biomes, crafting items, and the narrative until the official launch.

Elsewhere on the charts, the original Subnautica and Subnautica: Below Zero saw a boost in interest thanks to discount offers coinciding with the pre-sale. Meanwhile, the camping exploration title 'Outbound', which launched on the 11th, snagged third place.

As for the daily peak Concurrent Players, we’ve seen the likes of Crimson Desert and Geometry Dash slide out of the top 20. Warframe, however, climbed to 19th place with 72,659 Concurrent Players, maintaining a strong run of over 70,000 players for two months following its 'Jade Shadows' update. Apex Legends is also enjoying a resurgence, keeping its Concurrent Players in the high 200,000s for over a week since the new season dropped on the 5th.
