About Experiment 404
6 unique endings
More than 40 anomalies
You are a botanist participating in Experiment 404, your goal is to complete 12 sessions and report any unusual activities. Pay close attention to your surroundings and stay alert, or the looming overlord might decide to end the experiment early.
Gameplay
Anomalies may appear in Room 404. Spot them. Report them. Fail—and the chamber will punish you in ways most unnatural.
Remove weeds from the plants and dispose of them properly to satisfy the looming overlord watching your every move through the cameras.
Replayability
No two playthroughs are the same. Experiment 404 branches into 6 different endings, each shaped by your accuracy in spotting anomalies and the choices you make under pressure. Every action is logged by the unseen observer, deciding whether you earn freedom, revelation… or something far, far worse.
