Shooter games have been accused of glorifying and promoting violence and several games have been the cause of notable video game controversies . After school shootings in Erfurt , Emsdetten and Winnenden , German conservative politicians accused violent shooter games , most notably '' Counter Strike '' , to incite young gamers to run amok . Several attempts were made to banish the so-called " Killerspiele " ( killing games ) in Germany and the European Union . Shooter games were further criticised when Anders Breivik , perpetrator of the 2011 Norway attacks , claimed that he developed target acquisition skills by playing '' Call of Duty : Modern Warfare ''
