  EARLY PREVIEW OF COOP SUPPORTED RADIO MUSIC

• Added mods folder for new radio music system for vehicles

  • Added Radio player to Radioman

  • Fixed a radio music bug where in sequential mode it would favor odd songs ,

  • Added cooldown/request system to radio music system to protect “Spam”

  • Bug fixes to resolve looping and other cycle modes not working

  • Setup all vehicles to support radio music

  • Added Speaker Tower

  • F:\Steam\steamapps\common\Cepheus Protocol\CepheusProtocol\Mods\RadioMusic
    Putting music in this above folder in any manner will register to the game upon open. It will also detect any workshop mods now!

  • Mods\RadioMusic\”Category” Can be anything you want. People dont need the same folder loadout since music is determined by file unique identifiers.

    The UI is currently in progress. It uses a deterministic system for creating a unique ID regardless of computer. So you can share MP3s,waves or flacs and everyone can hear the music when played as long as the host has X song. Clients connected to a server can only play music that the host has locally.

  • You will need to enable -log as a launch argument to get the IDs that we generate when you open

  • Then after you open the game click on the window and Ctrl F to search for a music track or the keyword IndexRadioTracks. Then write down the ID’s or screenshot them.

  • 

  • You must select a Radioman, Speaker (buildable now) or Helicopter to try it out before you enter the console command!

A few times each week, our developers host public multiplayer sessions where we jump into the chaos ourselves—testing, refining, and showcasing the true state of the game. These sessions are open for everyone to join, chat, and experience the evolving sandbox that Cepheus Protocol Multiplayer and Singleplayer has become.

This particular session started with twelve players splitting into multiple fireteams, each setting up forward operating bases (FOBs) across the city. One team established their base in the center, another fortified the soccer field, while a third entrenched themselves near the construction site. Once Chelseys location was discovered, the teams coordinated to divide the map—back-capping the right side and containing her forces to the left.

The first major engagement came at the soccer field, where Chelseys infected army launched repeated assaults. Waves of brutes and juggernauts clashed against entrenched defenses while operators and RTS-controlled infantry fought street-to-street. When Chelsey shifted her focus toward the Bayfront Administration Center, the central fireteam held firm, repelling the push and stabilizing the front lines.

Meanwhile, Moro’s team conducted daring hit-and-run strikes deep in infected territory—keeping Chelsey off balance and forcing her to defend on multiple fronts. A few close calls nearly broke our lines, but through coordinated air support and precision strikes, we turned the tide. Soon after, our combined forces launched a decisive counteroffensive that pushed her back to the import-export district.

At the climax of the battle, Chelsey unleashed everything she had—massive infected hordes, explosive variants, and juggernauts charging the southern front. The push almost succeeded, but a quick call for reinforcements from Ford’s squad brought helicopters and operators roaring across the skyline. The ground units regrouped for a final unified assault, sweeping across the neighborhoods toward the lighthouse and satellite communications sectors.

In a storm of gunfire, missiles, and chaos, we finally pushed Chelseys forces back into the sea—securing a hard-fought victory. The battle ended with every surviving player lined up across the pacified coastline for a well-earned group screenshot.

This match marked one of our most successful multiplayer playtests yet—no crashes, minimal bugs, and over 90 minutes of pure, unscripted RTS/TPS mayhem. You can watch the full 1 hour and 28 minute playthrough below. Every week, sessions like this bring us closer to the vision of what Cepheus Protocol is meant to be: an RTS unlike anything else in the genre—alive, unpredictable, and built on the stories that emerge when real players face impossible odds together.

Thank you for your continued support as we rebuild Cepheus Protocol from the ground up. Every match, every bug fix, and every chaotic moment helps shape the future of the game.

Recap for those late to the party

https://store.steampowered.com/news/app/979640/view/537736957039477252https://store.steampowered.com/news/app/979640/view/537735054151909377

Immediate priorities are:

• Balancing the new Builder Drone and Juggernaut AI

• Wrapping helicopter polish (directed landings, pads, operator features, desync fixes)

• Fixing AI issues with enemy prioritization and tactical decisions

• Frequent bug fixes as we get reports

• Chelsey’s AI

• Juggernauts are undergoing testing at the moment

• Population Meter re-implemented at the bottom-left of the UI for tracking infection strength

Once helicopters and AI stability are locked in, focus will shift to Custom Game Options so players can tune pacing and difficulty. Vehicle driving AI and pathfinding are next in line, but we may hold off depending on the volume and severity of bug reports.

We are aiming to flip the rebuild into the default experience by the Halloween Sale, with older versions still available as an opt-in. The exact timing will be based on stability, bug reports, and community feedback — our goal is to get as many people as possible playing on the rebuild once it’s ready.

October priorities include:

• Implement the AJAX(HUMVEE) as a test bed for vehicle driving. Work with the community to establish a good “core” vehicle driving. After its “done” we start porting over all the wheeled vehicles and follow up with the Abrams and co.

• Extensive Bug hunts / Performance tweaks

• A save/load system for Pandemic

• Bay Area map updates: Treasure Island and Angel Island are under renovation, with rollout expected around Halloween. Stay tuned! We will aim to release this map in segments going into XMAS. Starting in stages

  1. Treasure Island->

  2. Angel & Alcatraz Island ->

  3. San Francisco North

  [carousel autoadvance=”true”][/carousel]

On top of these big-ticket items, there are many smaller details and fine-tuning tasks underway — some not listed here but discussed in recent CERC HQ broadcasts. October will be a mix of large features and constant iteration as we refine the fundamentals.

Cepheus Protocol | CERC HQ | #69

This week’s update is a no-holds-barred breakdown of Pandemic mode’s evolution, centered around the rebuild of Treasure Island and a total systems overhaul. Robert walks through the new layered rollout strategy for map expansion, beginning with a playable slice of Treasure Island set to launch around Halloween. With Unreal Engine 5’s precision fixes, the team can finally realize their original vision for a scalable, destructible, and immersive RTS battlefield.

Level design gets serious upgrades, including foliage placement, bridge logic, and terrain verticality—while the devs debate whether to support multi-tiered underpasses for gameplay. On the AI side, huge strides are made in how infected evaluate targets, spread, and adapt to player fortifications. Pathfinding gets tighter, blowup enemies are rebalanced, and new debug systems give devs visibility into AI logic mid-match.

Operators get more integration with RTS elements—riding helicopters, building structures, and coordinating in full co-op squads. Helicopter physics and weapon balance receive a full pass, alongside early work on ground vehicle deployment starting with the Ajax. Meanwhile, discussions begin on evolving infected variants and bringing dynamic civilian factions back with better AI direction systems.

Chelsea’s overhaul is still coming. Juggernaut and Builder units continue to be tested. And yes, feedback from Discord and Steam is actively shaping next steps.

• Treasure Island rebuild set for Halloween rollout with layered map expansion

• Fully revamped AI threat logic, pathfinding, and zone targeting

• Debate over under-bridge traversal and visibility in RTS gameplay

• Helicopter balancing complete: physics, flight feel, and weapon tuning

• Operators now ride, build, and interact deeply with RTS mechanics

• Juggernaut and Builder infected updated with smarter behaviors

• Upcoming work on vehicle AI, bridge destruction, and custom doctrines

• New debug tools help devs analyze AI decisions during play

• Feedback-driven dev cycle with live balance adjustments

• Community Q&A covers everything from faction AI to turtling tactics

Expect nerfs to blowup units, tweaks to helicopter refueling, and tighter threat evaluation logic. The Ajax vehicle rollout begins soon, and feedback is requested for bridge logic, underpass use, and unit camera control. It’s shaping up fast—get ready to test hard and break things.
