Blok is a psychological horror game set in 1990s Poland. You play as a former oppositionist who fled the country during the communist regime in the 1980s. After the system's collapse, a mysterious letter from your mother brings you back to your former home. But you sense something is wrong.

Years after fleeing the country for political reasons, you return to your old apartment block, brought back by a strange letter from your mother. The neighborhood seems to be the same. But something is not right. It is almost too perfect. And the more you search the more cracks you find.

Explore the neighborhood, solve environmental puzzles, and uncover the truth shaped by fear, silence, and control. Traces of life under a regime based on secrecy and repression. As you investigate, the world subtly transforms around you.
