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.

Absolutely amazing!

I enjoyed this mod, it was something new to me. It's been so long when episode 2 was released, when is episode 3 gonna happen?

Tried to enjoy it but it was just too frustrating and most of the time you're not even using your own portals.

Very well!
I hope to continue.

Good Game much story and Very lovefull made !


After playing Episode 2 all I can say is: ITS BEYOUND EPIC! This mod is short and sweet! It does it it suppose to really well and the ending was somewhat unexpected! Great mod, I can't recommend this enough! =D

I'm sorry, but the second episode just isn't... good. Func_physboxes, func_doors, and several-day compile times are impressive and all, but they aren't... fun. The mod is utter crap to play, and it's really amazed at itself. I bypass an entire puzzle with basic portal placement. "Ben goes happy face." The animation on the other test subject is appalling, with a typing scene where her hand shakes violently across the keyboard like she's going to have a seizure, and a scene where she "fixes" a generator by bashing it with a wrench that became invisible the instant it entered her hands (by pure luck; it took a few tries before she noticed I was stabbing her in the face). She seems to be the supposed leader, at least according to the storyline, so why the hell does she use squad AI mechanics and follow you around? Probably because she's a poorly scripted npc_citizen. All the "new and creative" elements have been seen before, either in Portal 2 or an existing Portal mod. I don't know if it gets better, given that I'm stuck at the turbine level. But so far, I'm not having fun.

Very well made mod. Well done.
