Revenge of Poopdeck Willie is a mod for registered Wolfenstein, made by Majik Monkee under the alias Elmer Fudd.
Initially released on August 20, 2004, it was re-released eleven days later with four extra levels and subtitled Resurrection. Some of these levels were based on maps that had previously appeared in Halls of Stonehenge.
Though the mod is intentionally humorous, it is also quite difficult. 12 levels are played over three episodes, and coding changes include increased health and ammo and changed episode names.
An SDL port was released on October 25, 2011.
