ENTITY: THE BLACK DAY is a tense horror game with action elements set in the dark catacombs of an abandoned complex. You are tasked with uncovering the truth, but every step forward reveals new horrors and doubts about the true enemy. Danger in every corridor As you explore the dark tunnels, you encounter the nightmarish remains of experiments. Empty laboratories, strange evidence, and twisted bodies point to a catastrophe hidden for too long. But the real threat is just waiting to happen. Every encounter forces you to make decisions: whether to use rare resources now or save them for far more terrifying encounters. Mistakes are costly — enemies are merciless, and each new boss turns the battle into a deadly test of strategy and reflexes. Game features Exploring an underground complex with a disturbing atmosphere. A resource shortage that requires a thoughtful approach. A system of medical injections for health restoration. Fights with unique bosses and their deadly moves.
