Ken Levine on BioShock DLC: wants to more replayability, not new narrative

BioShock isn't exactly the kind of game you expect downloadable content for. There's no multiplayer and the storyline doesn't lend itself to simply dropping in additional "levels." At the same time, unless you're interested in unlocking all the achievements, there isn't much motivation to play through the game a second or third time -- but creator Ken Levine of 2K Boston envisions that as how he'll approach the game's DLC.
