extra doom mod, is a mod for doom 2 with the aim of playing in Cooperative mode (Although it can also be single player) that adds many weapons, techniques and New Demons, All new Demons were taken from the Realm 667 (Credits To its creators) this is not the final version, since 100% is 90% complete. Enjoy the mod: D
This version of the mod only fixes bugs and replaces the bonus items that monsters give you with ones that don't count in the final counter after beating a level.
it is very good
Thanks bro! :D
