So I saw this youtube video  and was wondering how I could do this in hl2 hammer editor with npcs like citizens and combine and stuff. Maybe even an all brush recreation of free tv or some cool shit like that.

I went through the comments, according to the video creator, He said that it only works on XASH, and not on Source.
