Entity: The Black Day

A third-person survival horror action game set in dark, atmospheric underground environments, blending psychological suspense with intense combat.

The story follows Adam, a former special forces operative assigned a top-secret mission: investigate a supposedly abandoned underground bio-research facility and extract evidence proving the government’s involvement in funding a viral development program—one that spiraled out of control and killed thousands.

What begins as a simple data retrieval job quickly turns into a dangerous search for answers. Most of the facility’s personnel are dead—casualties of brutal emergency protocols. Two scientists are missing, and Adam must track them through dark, hazardous corridors and storm-drain tunnels.

As Adam follows their trail, unsettling signs and unexplained events make him question the true nature of his mission—and his own connection to the facility.
