It was originally labeled as a pitch for the future of Call of Duty, with no plan to create a finished product. "The intent was to create a sweet game pitch and see what people thought of it," Police Warfare producer Shawn Wallace tells Joystiq.

After the video exploded on YouTube, the team behind it realized they had hit on something. "There was such a strong response on YouTube from people who are clearly gamers who want this, which sort of validated our feelings for how strong the concept is," Wallace adds.

Today, Police Warfare becomes the next in a long line of indie projects looking for funding via Kickstarter.
