Into The Night
A demo titled "Exposition" was released by the 158th Banshee Squadron back in 2009. It features missions in both Earth's atmosphere and in space, as well as custom craft, weapons and other assets.
I really like the custom assets in this mod. The ships, the weapons, the skyboxes and so on. But from a mission design standpoint, it's not good. I think it has potential, but needs to be severely worked upon. -MrTealTwo
