Entity: The Black Day

Entity: The Black Day is a third-person survival horror action game set in underground environments. You play as Adam, a former special forces operative sent to investigate an abandoned bio-research facility and retrieve evidence of government funding for a viral development program that spiraled out of control and killed thousands. What begins as a data-retrieval mission becomes a search for answers: most of the facility’s personnel are dead after brutal emergency protocols, and two scientists are missing. Adam follows their trail through hazardous corridors and storm-drain tunnels as strange signs and unexplained events make him question his mission and his connection to the facility.

Combat and survival

You fight with firearms, melee strikes and evasive maneuvers, and can use brutal takedowns to crush or smash weakened enemies. New weapons unlock as you progress, while limited medical injections found along the way restore your strength. Ammunition can run low, so you can search for extra ammo and materials to craft more rounds and health injections. Bosses have distinct attack patterns and require different strategies.

Exploration and interaction

Levels contain hazards, puzzles and enemies. Some puzzles require you to combine clues from the game’s virtual environment and the real world, thinking beyond the screen to solve them. Adam also has an algorithm-driven interaction system: he reacts to situations, shares his thoughts, speaks directly to you and sometimes breaks the fourth wall. You can customize how much he interacts; the system is not generative AI.

The Operative DLC

The included The Operative DLC continues the story after the main game’s ending. You play as Ethan Carter in a first-person experience focused on narrative and exploration, learning more about “The Black Day Project,” a secret government project conducted at the highly classified Area 1107 research facility. The story continues from a new perspective, revealing more about the project’s background, purpose and surrounding events.

A standard playthrough takes approximately 6 hours: about 4 hours for the main game and 2 hours for The Operative DLC.
