"SOMNIUS," a chaotic escape game supporting up to 6 players, is now available on Steam Early Access! Use the "vacuum gun" to suck up your friends—and everything else—and turn them into bullets.

STFGames, known for developing *Stone Simulator*, launched early access on Steam on September 22 for *SOMNIUS*, a cooperative escape game that supports up to six players.

Use the “Vacuum Gun” to suck up anything and turn it into bullets!

This cooperative escape game, playable by up to six players, challenges you to convert everything in a crumbling dream world into portal energy to escape. Armed with the “Vacuum Gun”—which can suck up and fire anything—you’ll collect every object in the room and feed them into portals, aiming to complete the portal network while preserving the dream world.

The Vacuum Gun is not only a tool for completing the portal, but also serves as a weapon, a means of transportation, and a versatile item that proves useful in countless situations—it is the very foundation of the game. Whether you choose to steadily work toward opening the portal or use the Vacuum Gun to blast monsters to ensure your safety, your strategic judgment will be put to the test as you decide how to handle the objects you’ve sucked up. Of course, you can even fire at your teammates.

Key Features

  • Play solo or team up with up to five friends.

  • Explore a procedurally generated dream world filled with bizarre rooms and dangerous creatures.

  • Suck in objects and fire them back at enemies.

  • Drop objects into portals to extend everyone’s remaining time.

  • Rescue downed teammates and use physics to adapt on the fly.

  • You can chat via proximity voice chat—but don’t forget that the monsters can hear you, too.


“SOMNIUS,” in which you must rescue the dream’s owner before everything vanishes, is currently available in Early Access for PC (Steam). The price is 1,050 yen, but until September 30, you can purchase it for 651 yen—a 38% discount. The Early Access period is scheduled to last approximately one year.
