The official premise
The official Roblox description (checked 2026-10-08) sets the scene in five lines: “EMOTIA - where every dying human's last emotion defines their afterlife” and “The Emotion Prison has been taken over by Corrupted Emotians.” Players “team up with up to four friends to venture deep into the dungeon-like prison, full of puzzles and mysteries”, cleanse the Corrupted Emotians, and “bring peace to the Emotion Prison”. The description closes with the line that defines its co-op design: “you cannot do this alone.”
Roblox files the experience under the Survival and Escape genres, and every server holds up to 25 accounts — your run party is a subset of that, capped at five players by the feature list. The experience is marked as a Beta, which is why features keep arriving with retitled updates.
