An update to an AI system in space exploration videogame Elite Dangerous that caused enemies' spaceships to become extremely powerful and aggressive resulted in a backlash by the game's users. 

Developed by Frontier Development and released in 2015, Eite Dangerous is a massively multiplayer online game in which the players' actions can affect the story outcomes. 

However, the '2.1 Engineers' update strengthened the capabilities of the enemy spaceships to such an extent they were able to craft their own lethal weaponry. 

Frontier said it believed the update shipped with a networking issue that let the AI merge weapon statistics and abilities, thereby causing unusual weapon attacks. 

The company was forced to remove the upgrade and strip the spaceships of their upgraded weapons, and reimburse players of their insurance payouts over the period the update was in place.
