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.

That was a lovely mod!
Question; is an Episode 3 planned? That didn't seem like a proper ending, but I don't see any official info on a 3rd episode.

Factum Solus is a good mod. Although I could not count the number of texture and graphics errors it was well done. I really liked the custom particle systems used and another human in the game. The tests were not bad, however fairly easy. I really liked the custom AI voice and all the particle systems.

Technically impressive, UTTER CRAP to play.
Cheap timed levels all around.
