Friends, grab your floaties......it's release day for The Aquatic Planet Pack! This DLC features a plethora of pool-dwelling critters, flooded flora and submersible buildings...and Duplicants who learn to swim for the very first time in ONI history!

There are brand-new biomes, plants, resources, foods and buildings, plus two new recruits—including one who's unnaturally well-adapted to the environment. (And needs to be convinced to join you.)

- The Aquatic Planet Pack DLC launches next Thursday, June 11th! - 4 June 2026
Ahoy, friends! The Aquatic Planet Pack DLC launches next Thursday, June 11th! It'll be available on Steam, WeGame, and Epic. This is the splashiest DLC we've shipped to date: for the first time ever, Duplicants are learning to swim! They've also learned how to perform CPR, which comes up about as often as you might expect. Immerse yourself in a flooded starting world where Duplicants hack open giant clams to harvest glossy pearls, swim alongside blindingly bioluminescent Beakon fish, and call Seaquines over to the Aquatic Milking Station to harvest the ingredients for Caviar. Mussel Sprouts and sticky Slogo snails populate the beaches, while Glo Squids prowl the depths of the abyssal trenches. Pulverize the wood from an otherworldly palm tree to extract the latex needed to produce rubber at the new vulcanizer building. This versatile material enables your Duplicants to craft rubber boot…
