Details on the specific titles are slim, with Epic merely listing the projects as "unannounced." However, 2K president Christoph Hartmann praised UE3 for the ease at which it allows simultaneous PC and console development, suggesting that the games could hit PC, Xbox 360 and PlayStation 3.

At least one of those titles is likely to be a sequel to the UE3-powered BioShock, as 2K owner Take-Two Interactive has expressed its interest in turning the underwater shooter into an ongoing franchise. Another title in the UFO-centric X-COM series has been rumored as well.

Last fall, job listings indicated that the next project out of 2K's Boston studio would utilize UE3. Formerly known as Irrational Games, 2K Boston and 2K Australia were the studios directly responsible for BioShock.

2K Games also recently announced the opening of 2K Marin, a new studio located at 2K's headquarters in Novato, California. No projects have been announced for the studio, though it reportedly consists of ex-BioShock staff.
