People Can Fly have produced a playable parody of the hit Call of Duty game series called Duty Calls: The Calm Before the Storm.
Taking aim at the common sorts of gameplay elements in many modern day first-person shooters, Duty Calls is a 700MB freely downloadable game which has already gained applause from like-minded gaming enthusiasts.
"Here's your objective: Blah blah blah secret base. Blah blah blah nuclear missile bomb. Blah blah blah counting on you. Good luck," says the introductory mission briefing.
The game can be downloaded from the Duty Calls web site or you can view the video trailer below:
