Factum Solus is a story driven episodic Portal mod. Player plays as Chell from the original Portal, but in a totally new exciting universe where the Aperture center is not controlled by GLaDOS but a AI called Ben.
As the player goes through new, creative and well thought out puzzles, she discovers that there is someone watching her. Someone not from the staff of the Enrichment center. Who could it be? This person becomes a big role in the story of Factum Solus and they work together to beat the chambers in Factum Solus: Episode Two.

If you want a proper fix on this mod the follow this tutorial:

First Download Both Factum Solus and Portal Project Beta:"https://www.moddb.com/mods/portal-project-beta1/downloads/portal-project-beta2"

Then Install Source SDK Base 2013

Go to Properties and then Click Beta

Then Click "-upcoming upcoming"

Then Put Portal-Project Beta into "sourcemods"

Once you have that get Source Unpack and just take portals Models and Materials Folders and copy them to Project-Beta

Then Copy EVERYTHING from Factum Solus to your Modified Project Beta

Restart Steam and Everything Should Work Credit to Project Beta for Making this fix
Possible!

Enjoy Your Factum Solus!

If you have a white screen when starting the mod, you need to download this: Drive.google.com and move the Factum Souls folder to C:/Steam/ steamapps/sourcemods.

Now the mod should work (this is a fix for the second episode only)

Yay! Thank you for that paste-in! I wonder what went wrong that this fix is necessary. Probably had something to do with steampipe I bet
