Just finished the DLC 100%, with all the trophies and everything. God, those last two stages were FANTASTIC. The 2nd stage in particular probably had the best platforming sections in the game, since they were quite hazardous. Laura was surprisingly fun to play as, what with her speedy, indefinate, and invincible mist-dodge and the lightning stream move you can do by holding down square. Also, sucking the blood out of ghouls is really, really awesome. Puzzles were top-notch.
The ending was pretty cool, wasn't expecting things to go down that way. Can't wait to see what happens next.
...also, beating the DLC opens up a new art gallery section that has stylized illustrations of the individual developers.
