The Duplicants plunge into a world beneath the waves, where they will either sink...or learn to swim for the first time in ONI history!

Open the floodgates of The Aquatic Planet Pack to explore the uncharted waters of a new starting planet awash with marine biomes, bioluminescent plants and critters, expanded aquatic ranching, and splashy Duplicant action. 

New Duplicant Skill Unlocked

Train your Duplicants to swim, and watch them cannonball right into the deep end! Once they've mastered nautical navigation, they can focus on colony-building instead of worrying about the pool being a little chilly.

They might still care about coworkers peeing in the pool, though.

Unreal Aquaculture

Explore flooded biomes full of remarkable marine critters, geysers, and plants that provide new foods, building materials, and even oxygen—including a puffed-up fish that drowning Dupes can sneak a life-saving breath from. It's everything an underwater colony needs to keep both their workers and their industrial expansion efforts afloat.

All-New Elements

Uncover a world of new elements that fuel construction, power, productivity, and refinement. Rubber production is especially useful, as it's used to craft higher-voltage insulated wires and rubber boots that prevent Duplicants' feet from getting too soggy. 

Seaworthy Styles

Transform your colony into a bastion of nautical style with more than 100 new cosmetic blueprints! You'll find a deluge of cool new paintings, buildings, outfits, Atmo Suits and more in the Supply Closet. 

Sole Survivor

Recruit a strangely evolved Duplicant from another colony! Somewhere between the sandy beaches and the deepest trenches of the abyss, this lone inhabitant lingers, watching closely to see whether yours is a colony worth joining... 

New biomes to traverse, critters to tame, and resources to discover—dive into it all with The Aquatic Planet Pack!
