WOOO is 32 level joke WAD for Doom II, requiring a ZDoom based source port. Similar to Mock 2: The Speed of Stupid, the WAD relies on ridiculous enemy placement, gratuitous abuse of ZDoom features, and intentionally terrible map design. The WAD was uploaded on /idgames archive on October 25, 2013. At the Cacowards 2013 it was highlighted in a "Sing the Praises of Pants" sidebar. The sequel, WOOO 2, was released a year later.
