The longest marathon playing an action-adventure videogame lasted 109 hours exactly and was achieved by Tony Desmet, Jesse Rebmann and Jeffrey Gamon (all Belgium) who played Assassin’s Creed: Brotherhood (Ubisoft, 2010), at the GUNKtv World Record Gaming Event in Antwerp, Belgium, from 18 to 22 December 2010.

The record attempt started with 20 participants. The three record holders were the only ones who were able to survive to the end.
