Guns and Glory is a mod for registered Wolfenstein, made by Ian Summerfield. It was released on September 19, 2007.
It features 31 levels spread across several episodes and a huge number of new graphics. Some have been lifted from DOOM but there are many original actors as well, including baboons, spiders, and numerous supernatural beings in addition to many new guards.
The source code changes include animated floors and ceilings, textured floors and ceilings, many new weapons and many new enemies.
The mod would be revisited in 2012 and 2015 as Guns and Glory 0.5: The Story Retold. The original 2007 version remains available only in DOS.
