About this game

It is true that most days at the Plague Control Department involve paperwork, inspections, and arguing with coworkers under flickering fluorescent lights but…is it always like this?

A deadly new infection is spreading across Spain…As the new recruit you'll work alongside a team of eccentric civil servants investigating cases that become increasingly disturbing with every new discovery.

Step inside the shoes of Hugo, a rookie officer thrown into a job far beyond his expectations. Between paperwork, investigations, awkward coworkers, and endless bureaucracy, you'll slowly learn what it really means to work for the PCD.

But the office is only the beginning...

Once deployed into the field, routine investigations turn into desperate survival missions. Explore contaminated zones, abandoned facilities, and dangerous environments while searching for clues behind the infection. The deeper you investigate, the clearer it becomes that this disease may not be natural and that forces far greater than the PCD are involved.

Alongside a partner who's difficult to trust and a cast of strange personalities, Hugo must uncover the truth before the outbreak consumes everything.
