Alien Vendetta

Alien Vendetta (av.wad) is a 2001 megawad that contains 32 new and hard levels. It is one of the few PWADs that are allowed to be used in Compet-n speedruns, and one of the Top 100 WADs of All Time. In a 2019 article on the history of Doom mapping, Alien Vendetta was called "the most influential PWAD of all time".

On August 1, 2016, the expansion Alien Vendetta: Black Label (avbl_v1.wad) was released on the megawad's website, coinciding with a revamp of the site's design. The wad features two new levels that replace MAP01 and MAP02, designed to then-modern level design standards.
