Alex from
our Discord channel is doing a mod based on the leaked Aftermath/Episodes VMFs.
Currently all maps up to ep2_outland_07 are ready and when he will finish ep2_outland_08, he promises to release a first demo of his mod so anyone can play it.
Basically it is the first such attempt to recreate an older version of Episode Two, that was publicly announced.
You can discuss this mod, ask it's author a question, and if you want to, join him in this attempt
on his mod's Discord channel. In particular he needs a help with porting old features from Source 2004-2006 version into Source 2013.
You can already find some of this maps fixed by Alex in our site's
Downloads section.
