About This Game

It was supposed to be a breakthrough.

Deep inside a classified medical research facility, scientists were developing an experimental treatment designed to do the impossible: force damaged human cells to regenerate fast enough to defeat cancer.

It worked. Then someone died, and came back.

What began as a promising cancer treatment became something far more dangerous. The human body had learned how to survive death — but regeneration was never meant to continue without limits. 

You are Alpha One, a private military contractor sent into the facility after all communication suddenly goes dark. Your mission is simple: determine what happened, locate any survivors, and recover the research.

But the deeper you descend into the complex, the less anything makes sense.

The halls are filled with dead researchers, abandoned experiments, and horribly mutated patients whose bodies continue trying to repair themselves long after they should have died. Damaged organs regenerate incorrectly. Broken bones grow back twisted. Flesh refuses to decay.

SURVIVAL HORROR RETURNS

Explore a dark, atmospheric medical facility filled with secrets, locked laboratories, hidden passages, and increasingly disturbing experiments.

Conserve ammunition, search for supplies, and decide when to fight—and when running may be the better option.

Face infected personnel, failed experiments, and horrifying mutations created by research that was never meant to leave the laboratory.

Enter the facility. Find the survivors. Uncover the truth. Survive what they created.
