In Bioshock, which was released in August last year for Xbox 360 and PC, players enter the game as a castaway in Rapture, an underwater utopia torn apart by civil war.

Caught between powerful forces and hunted down by genetically modified "splicers" and deadly security systems, players have to come to grips with a dangerous and mysterious world filled with powerful technology and fascinating characters. With multiple avenues for surmounting challenges on both a moral and tactical level, no encounter ever plays out the same.

Nearly everything in the game can be turned into a weapon; players can biologically modify their bodies with plasmids, hack devices and systems, upgrade weapons and craft new ammo variants, and experiment with different battle techniques.

Last month 2K Games has announced that it has signed an agreement with Digital Extremes to assist in the development of BioShock for the PS 3.

Digital Extremes pioneered technological and graphical design within the video gaming industry as the co-creators of Epic Games' Unreal franchise. Using the experience it gained from working on the recently released Dark Sector, Digital Extremes will help 2K studios to optimize BioShock's performance on PS3.

2K Games has offered also some details about the new features whioch will be included in the new version such as  the Survivor difficulty mode, Trophy support and the addition of all-new Add-On Game Content.

Also, exclusively for the PS3 the game makers have created the Challenge Rooms, which

will test the mettle of new and seasoned gamers by requiring them to utilize the knowledge and skills they have learned while traversing the halls of Rapture. The first Challenge Room will be presented at Games Convention 2008 a nd will be available for download shortly after launch.
