Chaos League is a fantasy-based sports management game developed by Cyanide Studios and published by Digital Jesters. It was released in Europe on 8 August 2004 and later in North America on 8 March 2005. The game is a spin on American football, the violence of the Medieval football with no rules and rugby-style of sports yet set in a fantasy world with teams being made up of fantasy races such as dwarves, elves, orcs and undead, along with the use of magic and other fictional elements during a "match". The tone of the game is satirical with comedic color commentary and adverts for fictional in-game universe products. An official expansion was later released in 2005 bundled with the original, titled Chaos League: Sudden Death that added new features and gameplay tweaks.
