BioShock: The Collection appears to be 2K’s worst-kept secret as yet another ratings board has rated the upcoming compilation, this time, the US Entertainment Software Rating Board (ESRB).

According to the ESRB listing, BioShock: The Collection will include the original BioShock, BioShock 2, and BioShock: Infinite, which we thought would be the case when we first heard the compilation was rated in Brazil. Shortly after being rated in Brazil, the compilation was rated by the Taiwan rating board, giving even more credibility to its existence.

While the ESRB rating confirms BioShock, BioShock 2, and BioShock: Infinite, what it doesn't tell us if all DLC will be included in the Collection. Considering this is being touted as the "Collection" of BioShock games, we would be very surprised if it also didn't come with all previously-released DLC.

BioShock: The Collection is expected to be released on PC, PlayStation 4, and Xbox One and has been awarded a Mature rating.
