Bulletstorm’s developers have had a bit of fun and released a free to download spoof of Call of Duty.

Duty Calls is described as "the most epically epic game of all time", it’s around five minutes long and is, of course, a first-person shooter. Electronic Arts have released it, and it’s available now to download.

Features include:

    * Duty Vision™ slows down the action so you can unload a storm of bullets
    * Immersive dialogue from the front lines
    * Cold, calculated realism
    * Killing animations motion captured from real actors
    * True-life reloading system allows for mistakes in putting the cartridge in the gun
    * Iconic sound effects
    * Thwart an enemy threat that could topple the country and possibly the world
    * Significant and historically accurate props
