MetaDoom is a randomizer gameplay mod by Kinsie, that serves to add elements from several games in the DOOM series, including mainline games, spin offs, ports and the press release beta. The mod adds new sounds, sprites, effects and gameplay changes to resemble and reference multiple DOOM games while still trying to keep some balance within the core gameplay. While introducing content such as new weapons and enemies, the mod has a special randomization system that handles the placement of the weapons and enemies, in which it can be affected by the player's progression through the maps.
