With their MONSTROUS difficulty, their MASSIVE slaughter, and their MONUMENTALLY elegant epic design... the maps of Sunder have some of the most influential architecture among the classic doom community. They were initially released in 2009, but the author, Insane Gazebo has just been adding new maps, fixing old maps, and still making changes and updates to Sunder to this very day. So this is Insane Gazebo's on-going long-term passion project.
This video is my first time playthrough of Sunder2512.wad map 21. The most recent released Sunder map and the last one in the set, so far. This is where the Sunder journey ends, at least until Insane Gazebo releases map 22. "The Leviathan's Arteries" is a very visually distinctive map with some mean fights; many of which, unfortunately, lagged extensively on my machine. It was still playable, but my hardware is really showing it's age...
