Greenhouse is a first person exploration game set within the overgrown remains of a botanical facility long since abandoned. You play as a psychic investigator piecing together why this place was shut down and what became of the groundskeeper who once tended its gardens.
The investigation unfolds through examining clues scattered throughout the environment and interpreting visions that reveal fragments of the past. You wander through lush gardens that have grown wild, eerie corridors where something feels wrong, and liminal spaces that exist somewhere between the familiar and the unsettling. Your character photographs each newly discovered area, building a visual record you can consult to track which corners of this sprawling place remain unexplored. The facility is designed as an open world with no loading screens between areas, keeping you immersed as foliage bends and rustles when you brush past it and water ripples around your legs, slowing your movement as you wade through.
Physics and perspective puzzles block your path forward, some randomised so they change with each playthrough. You can manipulate the weather itself by picking up objects like umbrellas, beach balls or sunglasses, shifting conditions between rain, hail and sunshine to set the mood anywhere from comforting to deeply eerie. The experience can be tailored to your preference. You might choose a haunting walk filled with beauty and dread, wandering alone through the atmosphere. Or you can enable entities and jump scares individually, fending off venomous insects with bug spray and encountering ghosts who may offer help or attack without warning. If you see the Groundskeeper, run.
