2K has announced the final downloadable content pack for BioShock 2, called Minerva’s Den.

The pack is a self-contained singleplayer experience that will put players in control of a new character that teams up with Dr. Brigid Tenenbaum to “unravel a dictator's stranglehold” on the new district of Rapture Central Computing.

The DLC will include new weaponry, a new plasmid mutation, more dangerous splicers that command the power of the elements and upgraded security bots armed with lightning bolts and rockets, states the press release. Most interestingly, Minerva’s Den will introduce a never-before-seen new type of Big Daddy – the series’ distinctive mournful aquanauts. From what we can tell from the two released screenshots, below, this one appears to be airborne.

"Minerva's Den is a substantial addition that will give players more of what they're looking for: more story, more narrative, more gameplay and more of Rapture," said Christoph Hartmann, president of 2K. "The core team has created an exciting product that further enhances the mystery and allure of the world of Rapture. Minerva's Den will be a fitting conclusion to the BioShock 2 saga."
