Fear is better
together.

Something was stirring in the dark. It finally has a name.

Our next game · Just announced

Poopnauts

You clean up space. Space fights back.

Four astronauts are sent to fix broken spaceships using... poop. Nobody tells you what happened to the last crew. Grab your tools, do the job, sell the scrap, and stay away from whatever else is on board.

  • 1-4 player online co-op: things go wrong faster with friends
  • Every ship is different: you never know what you will find inside
  • Poop sticks to walls, floors and faces. Sometimes it saves your life
  • One of the things on board looks and sounds exactly like your friend

Coming Q2 2027 · Wishlisting takes 5 seconds and tells Steam to show Poopnauts to more people. It is the single biggest way to help us.

The studio

Small team.
Big scares.

Interactive Wave Studio is a small independent team based in Romania. We build the kind of horror we want to play with friends: tense, unpredictable, and just a little bit funny when someone screams into the mic.

Everything we ship is made hands-on: the ghosts, the maps, the jump scares, the mop physics. We update our games often and we read everything our community writes.
