According to Levine, "If you zip through it then it's not a hugely long experience but if you dig deep it's probably three hours plus, if you really dig deep. But it's not the longest thing in the world.
"I think there are definitely people who are like 'Well, I want hours and hours of gamplay'. I think if that is your primary metric, this probably isn't the thing for you. If you want to feel like 'Wow, I just got a whole new experience' - that's what you get out of this."
He went on to stated that "I don't read people's household budgets and I can't tell them what they should buy. We chose quality over quantity."
Levine admitted that the team could have gone the "easy route" and just done more Columbia with new powers, enemies and weaponry, but instead the team decided to "take all of game systems we designed in Infinite and modify them so they belong in Rapture," making a hybrid of BioShock 1 and BioShock 2 combat.
Part 1 of Burial at Sea is $15 standalone, and part of BioShock Infinite's Season Pass.
