7. Fort Frolic – BioShock
Ken Levine’s dystopian world of Rapture, the underwater city in which BioShock takes place, has no shortage of twisted elements. Class warfare led to the destruction of the city that was meant to serve as the technological utopia of the world. The game, which just celebrated its 10 year anniversary, still stands as a classic in the genre, and Fort Frolic is perhaps the most twisted and memorable section of the game.
The objective of the game’s seventh mission is simple – cross an entry hall and take a bathysphere to another level. However, when the player goes to do so, he is cut off by Sander Cohen, the crazy artist and playwright. The villain’s voice booms over the speakers as a new set of enemies, the Splicers, begin to attack you. The eeriness of the level design, as well as the unique design of the Splicers encased in plaster make this one of the most unforgettable missions in gaming.
