The fifth season of the action-comedy series Red vs. Blue and marks the end of The Blood Gulch Chronicles. Three new arrivals keep the Red and Blue armies on their toes as they fight, bicker and argue for control of the universe's most worthless piece of real estate -- a box canyon in the middle of nowhere. In the riotous conclusion of the series that took the Internet by storm, The Blood Gulch Chronicles return with the usual gang of luckless troops -- joined by a mysterious stranger, a half-alien child, and a crashed ship. Together they discover a hidden world that could finally answer the question, "Why are we here?"
