Red vs. Blue, often abbreviated as RvB, is a comic science fiction video web series created by Rooster Teeth Productions and distributed through the Internet and on DVD. The story centers on two opposing teams of soldiers fighting a civil war in the middle of a desolate box canyon (Blood Gulch) in a parody of first-person shooter (FPS) games, military life, and science fiction films. Initially intended to be a short series of six to eight episodes, the project quickly and unexpectedly achieved significant popularity following its Internet premiere on April 1, 2003. In its run, the series has had seventeen full seasons and five mini-series that extended the series' plot. The fifth season of the original Blood Gulch Chronicles series ended with episode 100, released on June 28, 2007.
