Yeah I requested to necro-post here, there's something small I wanna share.
Ever wanted to play the original Portal in Portal 2's updated engine and level style/design?
Last night I found someone making a mod for Portal 2 doing just that, and they have released a demo of the first few levels. It's something I was waiting for someone to do for a little while.
I dunno how I
missed his own showcase vid, but I did, and made my own vid (even though YouTube loves to corrupt my stuff lately). However one of my suggestions was that he should re-introduce the original soundtrack to retain some atmosphere from the original game, and my vid still demonstrates that (I added it in editing):
There are some bugs, and perhaps the starting chamber should be like the original and not look like the hotel room, but otherwise it looks very good. Will be keeping a close eye on this.
