(EDIT: Due to a number of events going on in my life, I must change the process of the Battle Station mode. The Battle Station mode will be featured in a separate map that takes place in the interior of the Eclipse. Apologies, everyone.). The Rebels must escort a bomb-carrier to the Eclipse's reactor. The Rebels will have three or four minutes to plant the bomb in the reactor room, while the Imperials have to keep the bomb from reaching the reactor. Time runs out, Empire wins. Reactor is destroyed, Rebels win.
How the Battle Station mode will work
sounds good to me!
