Between June 19 and 21, in a deserted Soviet military base near Leningrad, a LARP (live-action roleplay) game Fallout 2009: Ничто человеческое (Fallout 2009: Nothing Personal) based on the Fallout series took place. It was organized by the "Albion" group and ca. 300 fans took part in it, after months of preparations.
The LARP was set in 2257, 180 years after the Great War, between Fallout 2 and Fallout 3. The players dressed up as Brotherhood of Steel paladins and scribes, raiders, ghouls, super mutants and New California Rangers, while the game masters reconstructed Sierra Army Depot, Mariposa Military Base and New Reno, with bars, casinos and other institutions.
