Murder Spree 20

Murder Spree 20 was an event hosted on the Icelandic city of Polar Ventura, presumably the 20th entry of the Murder Spree series. A question on the Game Station's version of The Weakest Link asked what was the Icelandic city that hosted the event. (DW: Bad Wolf)

Murder Spree's description suggests it was a legal hosted event like the Olympics.
