MBOMBS is a modification for Quake by Frardog on September 28, 1996. This modification combines BOMBS8 with MORNING STAR 1.09b.
All parts of the BOMBS modification are included, suggesting it was used as the base. MORNING STAR does not include any of the custom obituaries, but does include the message when using impulse 112. Also note that the Morning Star is the server version, meaning no custom models are included.
