Boss Generals for Command and Conquer™ Generals Zero Hour is a huge mod project that's under works for 10 months now, and it should better be called an "expansion pack mod" due to its scope - 15 new revamped maps from the best available in the community, two new "Boss songs" for each faction - including an amazing intro soundscore from the CnC composing legend, Frank Klepacki, tons of new abilities and even new tech buildings.
