Epic Games has unleashed a free online game titled Duty Calls: The Calm Before the Storm as a way to promote Bulletstorm. The target of the open parody is clear: Activision and its Call of Duty series.

“Wow. I’m blown away,” wrote Epic Games’ Cliff Bleszinski on Twitter. “This game will redefine military shooters for years to come.”
