Minervas Den is a fantastic dlc, a beautiful addition to the canon. The story of sigma is one of tragedy and hopeless desperation. Sigma I really enjoyed the plot and how it opens up more about society in Rapture. The Thinker is a great idea and I wish this was a full game because I knew there was more to tell. The gameplay is obviously identical to BioShock 2, it’s really fun. This dlc just reminded me that I wish we had more of Rapture to see!
