Haven't really bothered to do Master Levels in Eternal since I got it a few weeks ago, so I might as well upload the attempt in which I beat them whenever I do. Will upload more of them, and then I plan on playing some Custom Master Levels. I currently have a Master Campaign mod I'm going through, but I may or may not upload that, depending on how challenging it is.
Btw mods included are just weapon, slayer and demon reskins, like you probably noticed. The only gameplay mod I have is just to increase the Slayer's walking speed as I didn't like the default speed. Other than that the rest of the game is vanilla.
