Ultimate editions of games always have all sorts of special features. When you grab BioShock: The Collection , the HD compilation that brings BioShock, BioShock 2 , and BioShock Infinite to the PlayStation 4, Xbox One, and PC, you’ll get to learn a little more about how the game was made. Irrational Games’ Ken Levine and Shawn Robertson will have things to say.
Not right away, though. People need to unlock BioShock: The Collection’ s developer commentary. There will be Golden Reel collectibles in levels. Finding them gives you more conversations between Levine and Robertson.
There’s a BioShock: The Collection video going over this feature, in case you need an example.
I like how this is being handled. For people who do want to hear the commentary, you get something to look for to unlock it. Those who don’t won’t have to collect the items tied to them or listen to them. Everyone wins.
