With Bulletstorm just arriving on store shelves today -- and possibly in your disc tray -- EA has announced the first batch of DLC. With the surprisingly unexplicit title of "Gun Sonata Pack," the DLC will add three new maps to the co-op Anarchy mode: Sewers of Stygia, Hotel Elysium and Villa.

The pack will also add two new Echo maps: Crash Site and Guns of Stygia. The DLC will be available for the Xbox 360 and PS3 "this spring" for 800 Microsoft Points and $9.99, respectively. The press release (after the break) makes no mention of a PC release for the DLC.
