Burial at Sea episode 1 was a big slog that I only managed to get through with sheer willpower and the fact that it was at most 4 hours long. Episode 2 on the other hand, is still about 4 hours long. But they were a lot more engaging due to a very drastic change in gameplay. Episode 2 eschews the same kind of fast paced shooting Infinite and Episode 1 had, and instead is more of a stealth game, very reminiscent of Dishonored and the like. You play as Elizabeth now, who isn't as adept in combat as Booker was in Infinite. So she crawls around, knocking enemies unconscious and escaping if need be. I found this gameplay to be very absorbing and enjoyable, to the point I beat this dlc is pretty much one sitting. As the last Bioshock thing to be released besides ports and remasters, Episode 2 is a bit disappointing. It tries its best to tie Infinite into original Bioshock, though it doesn't make sense at times. There's some interesting environments in this version of Rapture, including a school/daycare, which was pretty memorable.
