Recently, a dev build of Portal 2 was leaked. The build itself, disappointingly, didn't have much different from the Steam build we have now, as far as I'm aware (aside from stuff like photoshop settings and such). It
did have a few extra maps, but these were already leaked with the Companion Cube collection.
There was one thing I noticed: a file named
glados_flythru.dmx, a Source Filmmaker project file.
My original guess was it had something to do with the original Portal 2 teaser trailer, probably the scene of GLaDOS waking up (hence the name).
It called for the map
sp_glados_01.bsp, which we don't have. I checked the text in the file itself, and I found it calls for some objects like a playermodel
"e:\dev\main\game\portal2\models\player.mdl"And the portalgun
"e:\dev\main\game\portal2\models\weapons\v_portalgun.mdl"Other than that, I didn't gather much from it (can't understand a lick of it).
If anyone can check the file out in full, and see if something can be done/found, I'd appreciate it.
(The file, so you don't have to download the full dev build:
