The citizens of BioShock 2's undersea dystopia, Rapture, love them some ADAM -- especially when it's been freshly harvested by a Little Sister. It's with this in mind that Digital Extremes tweaked the tried-and-true Capture the Flag multiplayer contest to place one team in charge of abducting one of these adolescent creepsters while the other must lay their lives on the line to protect her.As the above first look at the mode explains, the "attacking" side's goal is to return the girl to a Little Sister vent. The defenders -- well they defend, of course ... but one of them gets to be a Big Daddy. We'll have our hands-on impressions of BioShock 2's single and multiplayer modes tomorrow, so look for more details then.
