Cepheus Protocol

Cepheus Protocol is an open-world real-time strategy military survival game. You command CERC (Center for Epidemic Research and Control) as it tries to stop the Pangu Virus from consuming the Bay Area. The virus turns the region’s inhabitants into infected swarms, and you must adapt, survive and reclaim control.

Command the response

You can direct the battlefield in real-time strategy mode or control the Operator in third-person shooter mode. In RTS mode, the Operator can also serve as a hero unit. You command land, sea and air forces against infected hordes that can infect and turn your units.

In Pandemic Mode, an aircraft carrier serves as your mobile base. If it is destroyed, you lose. Winters, now a rebuildable hero, can lead your forces as you defend the carrier. Up to 16 players can share control of CERC operations in co-op, pool resources and coordinate their tactics.

Progress and customize

Combat experience improves characters’ health and targeting efficiency. Leveling up through the Doctrine tree unlocks support options, weapons and units. You can also customize the Operator’s weapons, abilities and appearance, drive vehicles, and gain progression perks.

Pandemic Mode lets you adjust gameplay options, turn off infected types and create custom scenarios. The game’s AI hunts units based on what it can see and hear, so stealth can help you avoid overwhelming swarms.

The Bay Area

The maps cover sprawling urban environments with varied locations. You plan attacks and defenses, and manage civilian evacuations. Dynamic provincial events bring unexpected challenges as rogue civilian combatants and infected groups form across the map; your reputation and decisions shape the surrounding world.

Stop the infection

You research the Pangu Virus, an alien pathogen, and seek a way to kill Patient 0. Hunting Patient 0 and their lieutenants can slow the spread: destroy their expanding hordes before they consume every province.

Multiplayer and modes

Co-op supports up to 16 players in RTS/TPS hybrid combat. Players share control of CERC’s operations, pool resources and fight the infection together.
