The main mode
Escape mode
The only mode the badges recognise, and the only one with a way to actually finish.
Four lives, not three
The heads-up display shows three hearts, but there is a fourth state after they are gone — a last chance. Players who count only the hearts end up surprised in both directions. When it runs out you get a choice between reviving for Robux and returning to the lobby.
Dying is not a reset. You drop everything you were carrying on the spot and restart from the entrance, so a team-mate can recover your keys. In a full lobby a death costs time, not progress — which is why solo runs are much harder than the badge rates alone suggest.
There is no ending
If you came here looking for the Scream And Run ending, that is the answer: a badge and the lobby. Guides describing a hospital-bed finale or a lore reveal are describing something that is not in the game — we checked 27 recordings and none of it appears in any of them.
