The X-UNIVERSE mod is built in a modular platform, meaning you install what you want to be in the game. The purpose of this mod is for research, testing and perfecting parts of the game.
Only for moddb I have compiled the add-ons into a multipack for the x plugin manager. See read more to what is in it:
-> XUNIVERSE (Beta 2.0) v18.104.22.168
->-> Graphics Addon v0.0.0.2
->->-> Planet Enhancement Plug-in v0.0.0.2
->-> Music Addon v0.0.0.1
->-> X2 Addon v0.0.0.2
->->-> X3TC Map Plug-in v0.0.0.1
I have only added the add-ons which are currently worthy of going in.
