2K Games has revealed two "Collections" aimed for a North American release this week. The 2K Essentials Collection will contain the original BioShock, Borderlands, and XCOM: Enemy Unknown. The 2K Power Pack Collection on the other hand will be sequel-oriented, and will include The Darkness II, BioShock 2, and Mafia 2.
Both will be available digitally for the PlayStation 3 and Xbox 360. There's no word yet on a potential retail or PC release.
