(Usaré esto para reseñar toda la campaña cooperativa)

Es un muy buen y muy sólido modo co-op. Tiene el mismo nivel de carisma del juego original con pruebas aún más cabronas y una GLaDOS que continúa siendo de los mejores personajes jamás creados.
Y por supuesto, una historia super ridícula. Pero no sería Portal sin una de esas.

Story wise, a little unsatisfying and a bit anticlimactic; gameplay wise, very satisfying and brain busting.

I am going to use this for the entire Co-op campaign and 6th chamber. Honestly, it was better than the main game (it removed most of the story and dialogue), with some greater puzzles but still a lot of easy ones. Maybe it needed an "I've played Portal 2 before" button just to skip the easy tutorial ones in each chamber. The 6th chamber also ends out of nowhere, with no real payoff on the puzzle or ending. Still, it was a decent-sized campaign.

Difficulty curve was a little wonky, but co-op in general had some cool ideas. Not all of them were stellar, but they definitely made us think in general. The puzzles are the strongest part of Portal 2, so I don't mind blasting ~40 of them without much break for story or anything, though it's noticeably a little dryer. Teasing a boss fight and then just ending on nothing (for DLC) was kind of lame.

the base co-op levels were way too easy, so this is a welcome surprise! this dlc manages to still be just as funny as portal 2, and ramps up the difficulty to a 10 for a final hurrah. great to play with a friend.

i dont know how i didnt catch this before now, but i'm so glad to have completed it finally. what a treat.
