strange room in portal 

There's one in Half-Life 2: Episode 2 drive.google.com/drive/folders/1--Lzmx9qKBLGaWo-SFzVNEpcfttKsjyN Folder's name is encoded in base64, decodes to "PROBLEM"

I Don't think this is tied to any other ARG's from what I've seen so Far

maybe interloper? like a map that some demo generated?

Note: A demo can't generate, we don't know HOW the demos are generated but know they are actually CREATED and STORED instead of ai generated (other than the maps, the maps are MapGen) this is verified by one of the TF2 Demos. We practically don't know anything but since i just woke up and haven't checked if there are new recordings i might edit this @@fighterjetlover55

In later videos it's revealed that the rooms are also generated through a console command so it's definitely inspired by interloper

I'm going to be honest I didn't know what "interloper" was until now

erm,,,, techsnikally they might not even need it since glados reveals that they have warehouses full of em

I think it's an ARG

this is an arg
