This is a Boom compatible megawad replacement for The Ultimate Doom. It features 4 episodes with 9 levels each all themed in the vein of the original game. The levels are all levels that Chris Hansen has released either solo or as part of projects over the past 25 years. There are also a couple of new levels to fill in the gaps. "Hell's Bane" is oldschool Doom with a few Boom tricks behind the scenes.
