Star Wars: Interregnum is an upcoming mod for Sins of a Solar Empire: Rebellion that builds off of the highly successful Enhanced 4X Mod. Fleeing the unknown terror that is chasing the Vasari, the factions of Sins of a Solar Empire stumble on a temporary wormhole that takes them to a galaxy far, far away. The sudden arrival of armadas with trillions of refugees and thousands of warships between the events of Episodes 5 & 6 forever alters the Star Wars universe and plunges the galaxy into an unprecedented period of chaos and violence. Begun, a new conflict has.
Since we're looking at the Empire's tactical structures, there is no way that I can hide the Galaxy Gun. While the Empire under Darth Vader eliminated funding for most superweapons, focusing instead on conventional naval units, the Galaxy Gun project was already well on the way to completion by the Battle of Endor and was allowed to continue. Essentially a giant launching platform for sending massive particle disintegrator warheads into hyperspace, the Galaxy Gun could hit almost any target in the galaxy for any location, making it in many ways much more dangerous than the Death Star. In theory capable of destroying an entire planet, the Empire rarely used this capacity due to the cost of planet destroying warheads, fear of a public opinion backlash, and the simple fact that destroyed planets could not be reconquered. Instead, smaller warheads that superheated the target planet's atmosphere were deployed instead, killing the entire population of all but the most well shielded planets, allowing them to be easily recaptured.
Gameplay wise, the Galaxy Gun is very similar to the TEC's Novalith cannon. While the Galaxy Gun deals more damage and will almost always kill the planet's entire population, it does not inflict the over time trade and population debuff like the Novalith cannon does.
Special thanks to the modeler Suk Munky and Nomada Firefox of the Star Wars: Alliance for this structure.
