Alpha Accident: Terra Nova is a nine-level Ultimate Doom episode created by Eugene Guschin (Wraith777). It is an episode 1 replacement targeted at limit-removing ports, and includes several changes such as new textures and props, new music, and three new enemies through DeHackEd. After an initial release in February 2013 and multiple updates, it was uploaded to the /idgames archive on August 25, 2016.

Alpha Accident: Terra Nova received one of the 23rd Annual Cacowards.


The WAD includes several new enemies and items through the DEHACKED lump.
