8 Times DLC Ruined The Base Game
2. Burial At Sea - BioShock Infinite
BioShock Infinite's two-part Burial at Sea expansion remains one of the most polarising DLCs of all time, and for good reason.
The roughly four-hour mini-campaign sees Infinite's main characters Booker and Elizabeth transported into the underwater world of Rapture from the original BioShock, for an exercise in shameless fan service that really, really doesn't hold up on subsequent playthroughs.
If you're able to switch your brain off and just enjoy the ride, it's not awful, but if you're at all engaged with BioShock's lore and storytelling, it falls painfully flat.
By introducing numerous franchise retcons and undermining much of the established story and character work in both the original BioShock and Infinite, Burial at Sea actually makes them both worse in retrospect.
If Burial at Sea was a piece of non-canonical wish fulfilment and nothing else, it'd be palatable enough, but given that BioShock creator Ken Levine has confirmed it to be canon, it places an indelible stain on both Infinite and the original game, perhaps even killing the desire to return to either in the future.
