Russian World of WarCraft player, Хируко, has managed to unlock all of the game's 2057 achievements.
By unlocking all those achievements, Хируко accrued 21,995 achievement points. He also completed 205 of the game's 300 feats of strength.
Apparently, unlocking all those achievements required much more than spending all your waking hours in the game. In fact, Хируко devised a strategy where all of his guild members worked relentlessly to help him finish his achievements. Хируко and his guild chose a small PVP server to carry out their plan. About a quarter of the guild members tracked down and killed other top players to prevent them from beating Хируко to "Realm First" achievements. The rest of the members collected the items and materials he needed and handed them out to him so that he'd craft and level up his professions.
Using 3 monitors and powerful NVIDIA Quadro SLI setup, Хируко played 12 different characters simultaneously.
