This is the 2010 version of Portal Project-Beta. ;)
Put folder in C:\\steamapps\sourcemods and restart Steam and the Steam process in Task Manager.
is it from the archive?
Yes. You'll need to install 7-Zip or WinRAR in order to open the archive and get folder to the mod.
Wait what is this? I thought this mod was released last year so I'm confused. 2010 version? can someone explain?
I have no clue why it was released in 2010.
The mod was originally created by the Project-Beta team in 2010 as a fan-remake of Portal Beta. Sometime in 2016 they got some beta files from valve and began working on entirely re-making the real beta era of Portal using the real beta assets.
Is the uploader of this file with the Project-Beta team?
I am not sure.
By the way, I know the missing texture files for the side of the Auto-Portal bars. they are in Half-Life 2: Episode Two's folder. (ep2_pak_dir.vpk). Download GCFScape to get into the VPK folder. Once you've done that go into materials/models/debug, copy the debug folder and put it in PPB's materials/models folder.
