 The majority of games that have been banned for violence have been FPS games, and for this reason, Christian games in the FPS genre have struggled to overcome the blurring effects of the violence inherent to the genre.Games such as "Revelation 7" and "Xibalba", for instance, have attempted to avoid claims of violence by using "off the wall" absurdist humor with enemies such as flying, bat-winged clown heads (modeled after the biblical Jezebel) that shoot rays out of their nose, or alien Nazis (a mocking reference to Raëlian religious beliefs) Other Christian FPS games such as "Eternal War" have avoided the issue by expressing the view that justified violence is morally acceptable.Some of these games, despite containing objectively violent content, have been affirmatively labeled "non-violent video games" by marketers and faith-based non-violent gaming communities.
