It was leaked several times, but now it's official. Now it has a trailer. BioShock: The Collection is a thing that exists and you'll be able to buy it sooner than you might think.
September 13 to be precise.
BioShock: The Collection features BioShock, BioShock 2 and BioShock: Infinite. That's quite the collection — even if Infinite was a bit iffy in hindsight, it's still a beautiful video game and quite the experience.
The Collection features all the DLC, including Minerva's Den which was super good. Also, perhaps more interestingly, commentary from Ken Levine. I would listen to that.
