“Minerva’s Den” will be BioShock 2‘s final piece of downloadable content when it arrives on Xbox 360, PlayStation 3 and PC this fall. 2K Games announced the single-player focused expansion will have you taking control of an “all-new character,” to “unravel a dictator’s stranglehold” on the Rapture Central Computing district.

Developed by 2K Marin, the expansion — which has yet to receive a price — will feature a “never-before-seen” type of Big Daddy, new plasmids and additional weaponry. This is something different than the multiplayer-focused “Metro Pack” and the “Protector’s Trials” pack that surfaced earlier this week on Xbox 360 and PlayStation 3.
