So I just bought the PC version of Portal (my brother had the 360 version before).
Anyways, I was thinking that it might be cool to make a small map for portal sometime.
Well, so I turned on the Hammer Editor tool and I just made a very small map to see if it works.
Well, it worked and very well too. It was pretty fun to map for Portal, so who knows, I might just release a Portal map sometime!
I'm sure no-one expected me to do that
