I remember playing through this DLC by complete chance, on my playthrough of the series. I had only played Bioshock Infinite prior to starting this playthrough and remember only having a minimal liking for it.

Years later, after completing the original and the sequel, I started Minerva’s Den. It has gone on to be my favourite in the entire series of games.
The way it rewards you for exploring the world with upgrades, rather than just buying them from vending machines.
The story, with its twists and engaging boss fights was great.
The new weapons introduced were all fun to use and added to the gameplay.

My only gripe with it, was that it didn’t last longer.
