Re vs. Blue: The Blood Gulch Chronicles, often abbreviated as RvB, is a machinima comic science fiction video series created by Rooster Teeth Productions and distributed primarily through the Internet and DVD. The series chronicles the story of 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. Rooster Teeth therefore decided to extend the series; the fifth and final season ended with episode 100, released on June 28, 2007. Three mini-series have been spun off, the latest premiering on May 26, 2008.
