Meet Prism in MONOWAVE’s Co-op Trailer

Mono could use a little help, too.

Our co-op trailer introduces Prism, the companion you’ll control as player two.

Watch on YouTube

You play Mono. Your friend plays Prism.

While one of you guides Mono, the other can fly freely around the same screen as Prism, passing emotions to nearby creatures and helping with the puzzles. Block incoming projectiles or become a platform to help Mono across a tricky gap.

Together, you’ll help the spirits you meet work through their feelings. The full adventure is playable solo or in local two-player co-op.

Not in the same room? You can still play together.

MONOWAVE supports Steam Remote Play Together. Only the host needs to own and run the game. Your friend can accept an invitation and join without buying their own copy.

Launch the game, then invite your friend from your Steam Friends List. An internet connection is required, and your experience will depend on connection quality.

Before you play

  • Play solo or in local two-player co-op.
  • On PC, use two controllers or a keyboard and a controller.
  • Invite a friend online through Steam Remote Play Together.

MONOWAVE launches on Steam on September 16.
Add it to your wishlist if you’d like to play, whether on your own or with a friend.
