The aliens have caused the oceans to rise, plunging the world into the abyss. Survive, craft, and explore this mysterious underwater world. Build your base, defend it against relentless waves of enemies, and dive deep to uncover the secret that could stop the alien invasion once and for all!
World In The Abyss
SteamWorld In The Abyss is a survival game where you must fight for survival in a post-apocalyptic world created after an alien invasion. Surviving humans are left to live on open water and scavenge what remains of the old world. The world as we know it is slowly changing as mysterious creatures and strange flora take over. Is there any hope left for humanity, and can the invaders be stopped?

BUILD YOUR BASE
Build your floating home by scavenging resources left from the old world. Unlock, upgrade, and customize your home to help you survive. Grow farms, craft tools, manage scarce resources, and build boats to traverse the large open world.

DEFEND YOUR BASE
To survive, you’ll need to defend your base and resources from raiders and looters. Plan your base and upgrade your defenses. Craft weapons, armor, and gear to defend yourself (and raid others).

FIGHT BOSSES
Explore the ocean and encounter mysterious creatures lurking in the depths. Uncover new biomes and discover the location of powerful bosses. Craft a deep-dive suit and explore sunken cities and lost worlds.

SCAVENGE AND FIND RESOURCES
Scavenge what resources remain on islands, floating forts, and on the ocean floor. Collect and store resources vital for your survival. Use fishing and construct traps to collect food and water. Build drills and pumps to collect minerals, oil, and gas.
