2K Games tapped network TV to debut its launch trailer for Bioshock 2.   As reported in game blog Joystiq, the publisher took over a three-plus minute opening ad slot on last night s Late Night with Jimmy Fallon on NBC.  The blog rightfully laments the spot’s heavy reliance on non-gameplay footage, no doubt a surprising move for a launch trailer.  But to 2K’s credit, it s well designed to speak to the broad audience the publisher bought into.  The high fidelity visualization of the game and its premise gives people who may not be familiar with BioShock one heck of a compelling setup.  At the same time, even without in-game footage, it tries real hard to differentiate the game play in the sequel for anyone who experienced the first.
