While the game has yet to be officially announced, BioShock: The Collection receives a rating by the ESRB, strongly suggesting that the compilation is coming soon.

Despite keeping its cards close to its chest in relation to the alleged HD compilation of all three BioShock games, Take-Two Interactive's rumored BioShock: The Collection may not be a rumor for much longer if the evidence keeps piling up. Following an initial listing on South African retailer Raru's website, ratings from the Brazil Advisory Ratings Board and a Taiwanese regulation board, and some leaked BioShock box art, it's now the Entertainment Software Ratings Board's turn to bestow BioShock: The Collection with another rating.

Very recently, BioShock: The Collection appeared on the ESRB website, which indicates that the compilation is scheduled for release for PlayStation 4, Xbox One, and PC. The collection was given a "Mature" rating, which is unsurprising given all the violence and adult themes present in each BioShock title. Based on the ratings summary, which states that "this is a collection of three first-person shooters," it appears that the compilation will contain BioShock, BioShock 2, and BioShock Infinite. It is unknown whether the Burial at Sea DLC will be included in this compilation.

Having said all that, until Take-Two officially announces the existence of BioShock: The Collection, it's best to take all this evidence with a grain of salt. But, seeing as how Take-Two CEO Strauss Zelnick claimed that BioShock is a "really important franchise", it's not outside the realm of possibility that BioShock: The Collection will be announced at some point.

While gamers await for the confirmation of BioShock: The Collection's existence (or non-existence), as well as some more BioShock sequels, there's BioShock creator Ken Levine's next project to look forward to. After shutting down Irrational Games two years ago and moving on with a smaller development team, Levine has since been hard at work on his next game.

Not much has been revealed about Levine's upcoming game, other than it will be an open world first-person shooter. But with Levine recently explaining that his new game will be influenced by critically-acclaimed titles such as Fallout, Dark Souls, and his own System Shock 2, there are promising signs that Levine's upcoming title will be a worthy follow-up of sorts to the brilliant BioShock Infinite.

BioShock: The Collection may still be a rumor at this point, but there are many fans out there who are keen to revisit an HD rendition of Rapture and Columbia, a fact that Take-Two surely must be keeping tabs on.

BioShock: The Collection may have been given an ESRB rating, but Take-Two Interactive has yet to announce the title itself, much less a release date.
