Alien Vendetta

An influential Doom megawad known for its detailed and challenging level design. Alien Vendetta (aka AV) is a megawad that contains 32 new and hard levels. The levels are full of details and monsters. It is also one of the few PWADs that are allowed to be used in Compet-N speed runs. There have been two separate releases of Alien Vendetta. The second release, made when it was selected for usage on Compet-N, made various changes to almost all of the levels; the biggest change is the replacement of MAP25: Valley of Echoes with another map, MAP24: Clandestine Complex, as well as the relocation of the former MAP24: Demonic Hordes to MAP25.
