2K Games and Bethesda Softworks Announce BioShock® & The Elder Scrolls IV: Oblivion® Bundle

June 17, 2009 2K Games and Bethesda Softworks are teaming up to deliver a value-packed experience that combines 2006 Game of the Year Winner The Elder Scrolls IV: Oblivion with 2007 Game of the Year Winner BioShock into one complete package. Beginning July 7, the BioShock & The Elder Scrolls IV: Oblivion Bundle will be available in retailers across North America for an SRP of $39.99 on the Xbox 360® video game and entertainment system from Microsoft and $29.99 for Windows PCs.

With a combined bounty of more than 80 Game of the Year awards from the industry's top publications, the BioShock & The Elder Scrolls IV: Oblivion Bundle provide two critically acclaimed experiences that have set new benchmarks for their genres.

Taking the world by storm in 2006, Oblivion set a new benchmark for role-playing experiences for current-generation gaming. Lush visuals, expansive worlds and limitless character customization combine with unprecedented levels of player freedom and NPC interaction to form one of the most successful and critically acclaimed games ever created.

BioShock is the genetically enhanced shooter that weaved intricate storytelling with an intense and exciting journey though a decaying underwater Art Deco utopia gone mad. Caught between powerful forces and hunted down by mutated citizens, you are armed with a complete arsenal from simple revolvers to chemical throwers, but are also forced to genetically modify your DNA to create an even more deadly weapon: you.

The BioShock & The Elder Scrolls IV: Oblivion Bundle is rated M by the ESRB. For more information on BioShock please visit www.bioshockgame.com. For more information on Oblivion please visit www.elderscrolls.com.
It seems odd that such a partnership would just happen out of the blue. Is something bigger at work here?
