2K Games has released a new trailer from BioShock, showcasing the PS3 version which is available today across North America and starting with Friday across UK and Europe. Gamers 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 deadly, mysterious world filled with powerful technology and fascinating characters. No encounter ever plays out the same and no two gamers will play BioShock the same way. The PS3 version offers a brand new difficulty mode, Survivor, as well as Trophy support.
