Reoxia - Official Announcement Trailer

An intruder in a spacesuit has been spotted, leading to a call for backup and an intense firefight with grenades. The target is described as "empty" but must be killed. A conversation reveals the protagonist was helped to escape because they are "the pure one," uninfected by Earth's air. Their brain, organs, and blood are sought, but not for a cure. The objective is to "find the astronaut." The situation escalates with a man down, a shoulder shot, and a sector lost, prompting the command to "run."
