Each level in the wad is named after a metal song that came out prior to 2000. The midi soundtrack is assembled from various sources from inside and outside the Doom community, containing no bespoke tracks.

Doom is fast. DOOM(4) is fast-ish. By mixing the movement speed of the old Doom, with the jumping tricks of the new DOOM, this mod is aimed to be a very fast paced experience, therefore it can be quite challenging. Even though there are no hitscan-attacking monsters, their projectiles are "not too fast" at best, "holy crap, where did that come from" at worst. The projectile attacks are there to be dodge-able most of the time, so long as you are keeping an eye (and ear) on your surroundings. However, since this was created with the idea of also being playable on a mobile device via D-Touch, where movement and aiming are somewhat diminished, additional skills were added to fit whatever playing style you prefer. Whether you want a very easy experience with a ton of monsters, or a very difficult one with fewer enemies, it's all covered! This mod is also completely designed with multiplayer in mind via Zandronum, and extensive care was taken to ensure it works as intended in said port. Coop with your squad and kick major ass butt. Or jump into Deathmatch with the completely rebalanced weapons and see who's better at piling corpses

Demon Eclipse was a Doom II mod for GZDoom by Amuscaria (formerly Eriance). Originally intended to be told through the eyes of another marine escaping the invasion on Earth in during Doom II, Demon Eclipse went through multiple iterations but was ultimately dropped due to real-life and the loss of motivation for the project by the author. The project had succumbed to multiple rounds of scope-bloat and become too much to manage. The first episode of first dropped from the mod, but was later made standalone by Blue Shadow. The intent was to focus and refine the second episodes 'hell-tech' theme in the "Hell-Forged Edition", but that also fell thru in 2014. In 2017, Amuscaria had revive the project in a complete reboot of the second episode by the name of Hell-Forged, with a much narrower focus around the Gothic hell-tech theme.
