Ethan "GooberMan" Watson is a mapper who has made several maps for the ZDoom source port. He joined the Doom community in 2001. His maps were characterised by heavy use of scripting, new ZDoom features, and creative use of old ZDoom features to create a different type of playing experience in Doom. For example, Doom: The Arcade Game was designed to be a fast-paced money-chewing arcade game where the player started with a small time limit and had to kill enemies, collect items, perform certain actions, and find secrets to increase the timer.
