IGN Video now offers a new "Hunting the Big Sister" movie from BioShock 2 showing off about nine minutes of gameplay from 2K Games' upcoming waterlogged shooter sequel. The developer-narrated clip features interactions between your big daddiness and your little sister, demonstrates combat, shows off Rapture, and suggests the Big Sister is not to be trifled with. The clip is also now available for download from ActionTrip and Gamer's Hell.
