Cepheus Protocol: An Open-World RTS Military Survival Game

Cepheus Protocol is an open-world RTS military survival game about commanding CERC as the Pangu Virus spreads through the Bay Area, turning residents into infected swarms. The threat can also infect your units, making the fight against the outbreak a battle to hold the line.

Command land, sea, and air forces, or control the Operator directly in third-person shooter mode. In Pandemic Mode, an aircraft carrier serves as your mobile base; if it is destroyed, you lose. The game also supports cooperative play for up to 16 players.
