Greenhouse is a masterclass in botanical dread, proving that terror does not always require darkness; sometimes, it thrives in the verdant light. The game invites players into a sprawling, Victorian era conservatory that feels uncomfortably alive. What starts as a simple horticultural task quickly descends into a fight for sanity. The core fantasy here is unraveling a deep, biological mystery where the environment itself is the antagonist. You are not just gardening; you are surviving an ecosystem that wants to consume you.
