The menagerie of the Doom franchise.
MetaDoom takes bits and pieces of gameplay, enemies, and weapons from all the major Doom releases and integrates them all into a singular mod, combining different aspects together to streamline them all.
For example, the Machine Gun from Doom 3 has an alt-fire using the mini-missile launcher alternate firing mode from Doom 2016. Likewise, there is a wide bestiary of enemies that are slowly trickled in as the player gets more powerful, providing an ever-growing challenge.
