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".[1]

There have been two separate releases of Alien Vendetta. The second release, made in December 2002 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.

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 by Brad Spencer (Vorpal). It must be loaded alongside Alien Vendetta to play. Then in September 2016, the original 2001 version was re-released on the website as well.

Only one map has original music, the rest being a medley of existing songs. In 2021, a Doomworld community project created the Alien Vendetta MIDI Pack with custom songs, which was released on the 20th anniversary of Alien Vendetta's original release.

Compatibility note[edit]

To play AV with PrBoom, the complevel should be 2 (Doom v1.9).

To play it on versions of ZDoom older than 2.3.0, or ZDoom-derived ports with an old codebase, you have to set the compatibility options to "find shortest textures like Doom" (rather than like Boom) for MAP07: Showdown and to "self-referencing sectors don't block shots" for MAP15: Bulls on Parade. The current versions of ZDoom and GZDoom apply the appropriate compatibility options automatically.

  • The project was originally developed as "Alien Vindicta" in 1996, with a storyline involving the revenge of the Icon of the Sin.[2]
