ESCAPE PORTAL

Public beta candidate — version 0.0.37

Explore Escape the Backrooms with Portal 2’s Portal Gun. Select it with 4, fire blue with left click and orange with right click, and return to your normal items with 1–3. Place paired portals on suitable walls, floors and ceilings, look through their live views and carry momentum through them.

Requires your own installed copies of Escape the Backrooms and Portal 2. The gun’s original models, textures, animations and sounds are read from your Portal 2 installation; original game content is not included.

Play solo or use the original Steam lobbies for up to four players. Every player needs both games and the same mod version. Each player can use only their own portal pair; shared portal views and remote gun presentation are disabled in this build.

Multiplayer portal synchronization is experimental and not fully verified. Two-player joining, client portal travel and momentum still need verification. Internal network-message hiding has not passed testing. Whole-campaign compatibility is not fully verified.

Join through the game: the host opens Multiplayer and creates a lobby; friends accept the host’s Steam invite or choose Enter with Room Code using the host’s code. Melty does not automatically join the lobby.
