|MAP05: Eternity's Hatred|
MAYhem 2013 is an 11-level PWAD for Boom-compatible source ports, created by members of the Doomworld forums in May 2013. It was the second MAYhem event, and led by series founder TheMionicDonut. As well as being made in a month, there was an additional limitation of using only two monster types per map.
Although the goal was still to create a full megawad, the project gathered eleven maps, one fewer than its predecessor. After an extended period of procrastination following the end of the month, MAYhem 2013 was finally released on 10 March, 2014. It received mixed reviews.
