Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“Early Access lets episodes be published as they're finished, while still releasing updates for the same game under a single price. The experience is mainly narrative-driven, but it does include some gameplay mechanics that would benefit from feedback gathered early from players.”

Approximately how long will this game be in Early Access?

“The game will be fully finished somewhere between 2027 and 2029.

Chapter updates will take months to complete, so their release will be spaced apart. Updates meant to fix bugs and implement minor changes will release more frequently (as needed).”

How is the full version planned to differ from the Early Access version?

“Our game has a long story, so we divided it in 3 or 4 chapters. Full version will contain all episodes plus secondary, smaller stories involving the main cast of characters of our game.

We also plan on translating our game into various languages to be more accessible for everyone.”

What is the current state of the Early Access version?

“Playable, may contain some bugs as this is our first public version of the game (as of now). Contains the the main storyline of the 1st out of 3/4 chapters of the full game.

Secondary missions are not available for the moment.”

Will the game be priced differently during and after Early Access?

“The price will increase slightly before each chapter release.”

How are you planning on involving the Community in your development process?

“We take very seriously all the feedback received from our community to slowly shape the game into a fun and unique experience. This early access will allow us to not only hear opinions regarding the story, but also try the new puzzles and game mechanics being introduced in the game.”

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.

Alternate between office life and dangerous field expeditions
