Horde Co-op Mode now playable in the CERC HQ branch
We’re nearing the final stretch of Phase 1 of the rebuild — just 1–2 weeks to go — and to celebrate the milestone, we’re opening up access to the Experimental Horde Co-op Mode for all players during the Steam Summer Sale!
This is the biggest gameplay update yet for Cepheus Protocol, and it’s fully playable today.

A brand-new Horde Mode Co-op experience to serve as the “base” of our Rebuild
-
Supports up to 16 players in seamless RTS/TPS hybrid combat
-
Experimental rebuild under the new “cerc-hq-public” branch
-
Buggy but playable – we’re working on it every day, and we need your feedback!
-
Right-click Cepheus Protocol Experimental Branch (Granted when you buy the base game) in your Steam Library
-
Click Properties > Betas
-
Choose cerc-hq-public from the dropdown
-
Let Steam update the build and launch the game

More Operator customization will come online going into next week for Weapons. We will be adding more weapons on a per week basis as we finish phase 1.
The Half Moon Bay Horde map is available in this build for early testing, but we recommend using the “Co-op Horde” test map for the smoothest experience. Monterey Bay is in active iteration and may contain incomplete elements.
