UAC Ultra

UAC Ultra is a WAD originally released on March 28, 2010 by Jamie Bainbridge (Super Jamie) and Jon Vail (40oz) which requires a Boom-compatible source port. It makes exclusive use of a set of custom textures created by Vail, and features two new monsters. It consists of 11 levels, and an inescapable "credits" level which prevents the player from progressing into the standard Doom II level set.
