Porting the game to Steamworks was handled by Digital Extremes, , and the new Steam version of the game arrives with controller compatibility, Steam achievements, and support for Big Picture mode.

Additionally, the game's multiplayer has been tweaked to allow players to search for any game as opposed to specific modes, and levelling up will also require less experience points.

2K adds that players who purchased BioShock 2 through an alternative digital platform will also be able to activate the game on Steam, by redeeming the original product key purchased at the time. Activating BioShock 2 on Steam will also give players access to the multiplayer map packs, Protector Trials and Minerva's Den DLC.

BioShock 2, which was not developed by BioShock and BioShock Infinite developer Irrational Games, was released in 2010, and the PC version required the use of Microsoft's Games for Windows Live service up until now.
