WADs in idGames, ZANDRONUM, UNKNOWN
I thought that the old Dalek sprites from Doctor Who Doom were going to waste in that dusty old wad, so I took the sprites, edited and updated them and made a new improved monster out of them using the wonderful power of the Decorate lump. Use 'summon' command with 'Dalek1-5' to summon the monsters ingame, or place them in your map, this is a monster resource after all!
Random Imp Generator
Variety is always the best in games, in my opinion. After discovering the imp/dark imp variant packs on Realm667 and toying with them for a while, I thought it'd be cool to put them all together. Every imp in any Doom level this wad is loaded with has a chance to change into one of the many varieties of regular imps or dark imps.
