Minerva's Den is the first story based campaign DLC for BioShock 2 and takes place within the events of BioShock 2 its costs 800 Microsoft Points on the Xbox and $9.99 on the PS3.
Minerva's Den is a self-contained narrative experience that puts players in the role of another Alpha Series Big Daddy called Subject Sigma revived by Charles Milton Porter. He has teamed up with Brigid Tenenbaum to unravel Reed Wahl's stranglehold in Rapture Central Computing. Rapture Central Computing houses The Thinker, a gigantic super computer created by Porter and controlling the district.
This at heart gives a little background to what happened to Brigid Tenenbaum after she leaves Subject Delta with Augustus Sinclair, and why it was vital for her departure. I found Minerva's Den to be very worth while to any mad BioShock fan or for just anyone who enjoyed the single player of BioShock 2 and wanted more, in total I completed this in 3 hours on medium difficulty and paced myself quite well picking up any Audio Diaries I can find (which by the way tell three quarters of the story in Minerva's Den). There is one new weapon in the game called an Ion Lance which is a very direct hitting weapon that spews concentrated energy and temporary blinds the enemy, with a new weapon comes a new enemy which is the Lancer Big Daddy a golden suited diver equipped with the Ion Lance which I must admit is one tough (blinging) Big Daddy.
There are about 2 areas for Minerva's Den and are truly something different from the full game, the game designers (small as they are) get really creative with the use of bodies and using the map to make it much more creepier which you cant help to appreciate.
The storyline and conclusion is one I really admire and as always it is kept with the Rapture standards, even though the game more or less gave away the ending before it hit you I still managed to be surprised at a lot of parts but it made Rapture somewhat more interesting and hope the BioShock franchise doesn't move to far from Rapture.
Overall I extremly enjoyed my stay at Minerva's Den: ★ ★ ★ ★
