The good news is that TheMionicDonut's MAYhem became an annual institution where mapsets - sometimes a megaWAD's worth - are created. The unfortunate news is that its completion / polishing phase inevitably runs over the monthly time frame. MAYHEM12, for instance, saw its final release in November of the same year while MAYhem 2013 hung around until March of 2014. It isn't much bad news at all, though, especially considering how long projects usually languish on hard drives. The community still gets a brand new collection of levels to play and the contributing authors get to flex their muscles in a theme that they might not have otherwise experimented with. In this case it's twelve Boom-compatible levels for Doom II.
