The Dota2 game pits two teams of five against each other across a small map. Each player controls a hero and the aim is to invade and destroy the enemy's stronghold.
The fast-moving game demands quick reactions as many of the heroes have special abilities that are only triggered under certain conditions or are boosted if used in conjunction with those of other player-controlled characters.
Thunder Predator was one of several teams taking part in the South American qualifying competition for the Dota2 International that will take place in August.
The cheating is alleged to have taken place during one of the semi-finals for the event in which Thunder Predator took on Brazilian team Pain Gaming.
