I’m just gonna leave this here.
Name: t3h_OIFY Content & VMFs
Description: The source content of the t3h_OIFY community collaboration started back in 2008.
Downloads: You can download from mediafire or dropbox.
Notes: It’s over 70MB, so prepare yourself. Just extract to your ep2 directory if you want to edit. The FGD is included. I believe t3h_OIFY_prerelease.vmf is my most recent revision. Several of the I/O connections in the map are flawed too. I’m not even sure all the VMFs will load.
Warning: I have not touched this for about 2 years now, so expect a mess.
