This mod has the best level designs out of all the other big Portal 2 mods out there - every map looked gorgeous and had a ton of fine details that told the stories of the people who worked in Aperture. Lots of cool new environment designs too, such as the prototype chambers.

Lots of people call this mod Portal 3, and while I think it's silly when people do that, in my opinion this mod comes closest to bearing the title because of the level designs and the puzzles. The puzzles aren't as difficult as the ones in Portal Stories: Mel and Portal Reloaded, but they do require some thinking without becoming frustrating. My only grievance with the puzzles is that it felt like you backtrack through puzzle steps a lot, but that's time that I can spend absorbing the environments.

Unfortunately I think the mod falls flat in the story department - it starts out strong and appears to build to something interesting before coming to an abrupt halt. Despite that, the boss battle is still fun and easily my favourite among both Portal games and all mods, and it's difficult to complain about the ending considering the multiple hours of high quality preceding it (for free!!!!!)
