This paper theoretically and empirically explores cheating in MMORPGs. This paper conceptualises cheating in MMORPGs as a sociotechnical practice which draws upon a non-linear assemblage of human actors and non-human artefacts, in which the practice of cheating is the result or the outcome of an assemblage. We draw upon the assemblage conceptualizations proposed in  and  and on empirical data taken from a pilot study we have conducted during the period September-November 2008 and from an ethnography we are conducting in the MMORPG Tibia (http://www.tibia.com) since January 2009. This game in particular was chosen because CipSoft, the company that develops the game, launched an anticheating campaign at the beginning of 2009.
