Since shipping Irrational Games' opus BioShock Infinite in March, creative director Ken Levine is already hard at work penning the script to his next game. Levine began crafting his next work earlier today, he confirmed on Twitter.

When asked by a fan what inspires him, Levine rattled off a list of authors, films and television shows, running the gamut from composer Stephen Sondheim to the works of the Coen brothers, Steven Soderbergh and Stanley Kubrick. Levine also referenced the Don Draper chronicles, Mad Men. Of course, these are just works that inspire him; not necessarily the works that will directly inspire Irrational Games' next project, whatever that may be.
