A type of video game in which players shoot a gun or rocket at an ever-changing scene of "bad guys." Introduced in 1993, DOOM popularized the first-person shooter game with its 3D graphics.
The first person in the UK charged with making a gun using a 3D printer was Tendai Muswere in 2019. The 26-year-old, from Pimlico in London, was jailed for three years for manufacturing the firearm.
