Minerva's Den is a heartfelt and touching story that takes the best parts of Bioshock 2's gameplay and encapsulates it in a short and sweet story about human emotion. Hearing Porters desperation as he tries to recreate Pearls personality with The Thinker as he realises he's gone too far is heart-breaking, and the revelation that subject Sigma was Porter the whole time was great, though slightly predictable as the end nears.
