Two new levels behind new Hub doors: an empty city with a powered-down subway, and apartments that never end.
How to join The host starts a lobby and shares the room code shown in it; friends enter it on the "Enter with Room Code" screen or accept an invite. Public lobbies also show in the lobby list. Everyone playing needs this mashup from Melty.
Two new levels for Escape the Backrooms, reached through two new doors in The Hub.
Empty streets between endless towers. Shops with awnings, a canal crossed by bridges, half-built offices behind construction fences. Search the shops and building sites for 3 fuses, bring power to the fuse box beside the subway gate down in the station, and go through the gate onto the platform. The platform leads to Level 13.
Dim corridors of numbered doors that never end. Some doors open onto empty apartments. Something knocks behind the ones that stay shut. Find the key and open the door marked EXIT to return to The Hub.
Solo or co-op with up to 4 players. Everyone in the session needs the mashup. Join friends the usual way inside the game.
