About the Game

Breach Signal is a 1–6 player online co-op cosmic horror game. You’ve been recruited into the [REDACTED] program, an initiative led by the para-governmental Federal Normality Agency.

  • Your mission: investigate dimensional breaches, unstable phenomena that distort reality and open passages to the unknown.

  • Lead scientific expeditions: identify Anchor Objects, retrieve samples for the Agency, and confront the unexplainable.

  • Equipped with a cutting-edge technology case and investigation tools, you operate within a retrofuturistic 80s world soaked in cosmic horror and bureaucratic secrecy.

/!\ Once inside the Domes, all contact with the outside is lost.

  • Semi-Open Map

Explore a stylized, semi-open environment where you can get truly lost… for your own pleasure!

  • Procedural Investigations

Each expedition is different: randomized spawn points, evolving objectives and dynamic threats ensure no session feels the same.

  • Analog Tech & Tools

Use unique, retro-futuristic investigation devices such as signal tracker, sampler, scanners and more, to detect anomalous entities and objects.

Stay close to your team... What lies beyond remains unknown.

  • Team-Based Survival

Work together with 1–6 players in an expedition where communication is essential. 

  • Proximity Voice Chat

Use proximity voice chat to communicate with other recruits, or your Talkie to communicate from a greater range. But be careful, you may not be the only one listening... 

  • Efficient Deployment

Strategic team planning ensures maximum sample recovery! With more credits, better gear follows.

Make it back with samples... and some memories.
