Cepheus Protocol (v2026.08.20 & ALL DLC)

San Francisco becomes a collapsing quarantine zone where every hour lost gives the Pangu Virus more bodies, more territory, and more dangerous mutations. Cepheus Protocol blends real-time strategy with tense squad-level command, casting you as Captain Winter and the leader of CERC’s increasingly desperate containment operation. Its mood is grim and military-focused: streets that seem manageable in daylight can turn into lethal hunting grounds after dark, while the wider outbreak keeps advancing regardless of your plans. Saving civilians matters, but keeping the infection from escaping the city is the priority, even when those goals collide.

Command begins with establishing and expanding a CERC base, securing resources, recruiting personnel, and deciding which parts of the city are worth risking troops for. You deploy specialized operatives directly into the field, moving them through infected districts, rescuing survivors, completing objectives, and engaging swarms of virus-ridden enemies with firearms, explosives, vehicles, and support tools. Combat favors preparation and positioning over simple brute force; ammunition, vision, squad composition, and extraction routes all matter when an area starts to collapse. The central loop revolves around reclaiming city sectors before infection levels rise beyond control, while research and stronger units give you more options against escalating threats.

What distinguishes Cepheus Protocol from a standard zombie strategy game is its active, evolving outbreak system. Infection is not merely a backdrop for missions: it spreads through the map, creates practical pressure to act, and introduces increasingly formidable mutated enemies as the operation drags on. The large urban battlefield supports varied approaches, from cautious scouting and rescue work to forceful military sweeps, though it can punish careless commanders quickly. Players who enjoy the tension of They Are Billions, the tactical flexibility of XCOM, and the broad command structure of classic RTS games will find a compelling hybrid here, especially if they prefer managing a crisis that never waits politely for their army to be ready.
