This is a Repost. If you want to play this go Moddb.com . It can be installed without having to deal with another mod in your library.

For anyone interested, this is a map pack from 2012-2013 made by fu$ion.

I don't know if you have permission from him to post this here [I doubt that you do since he's been last online 8 years ago.]

If yes - Prove it and change your page to look nicer. And change the mod's app Id to the regular version of portal like everybody else.

If no - Delete it. Taking someone else's work and claiming it's yours will bring you nowhere.
