I SAW! That one takes place in Rapture! <3 Apparently the first little bit is with no combat (kinda like Infinite) and you get to explore Rapture pre-fall! WOOHOO!
I am very stoked for this.
Also, Rapture Elizabeth looks super sexy.
If the DLC is 1/4 as epic as Infinite's main story was, it will be great. ^_^
I played through Infinite so quickly. It was like a good book and I couldn't stop. It left me breathless. That's what I want in a game. It makes most games look like sh*t compared to it.
