We have been carefully listening to your feedback across our various community channels. Among the many suggestions, the most requested feature for our PvE Extraction Shooter was, without a doubt, the ability to survive and escape together with friends.

Today, we are excited to announce that we have officially decided to implement a Co-op Multiplayer Mode!

This update is being built on the Steam Networking (SDR) infrastructure. By utilizing Steam’s dedicated relay network, you will be able to enjoy a smooth, stable, and secure co-op experience with your friends—all without the need for private server setups.

Key Development Highlights:

  • Character-Based Progression: Each player will save their progress and data on an individual character basis.

  • Seamless World Hopping: You can take your character into other players' worlds or host your own world and invite friends to join you.

  • 4-Player Co-op: We are currently developing the game to support up to 4 players in a single world, surviving and fighting side-by-side.

Please keep in mind that specific details may change as development and optimization continue. We are committed to delivering the best possible experience for you.

Thank you for your incredible support!
