Spoilers, obviously.
First things first, I unlocked a "Projected Shadow Munitions Intensifier" after completing the "Allies Under Attack" nebula, and can't figure out what in the world it is; not under any champion tabs, build tabs, etc. I have the Zenith, Human, and Spire destroyers unlocked, and beating this nebula gave me access to the cruisers and the munitions intensifier. What is and how do I access this munitions intensifier thing? Google and forum search show nothing D:
Secondly, how does nebula experience work? Is the reward based on your current level when you beat the nebula, in addition to whatever other modifiers (how long it took to beat, life left on starbases), or is it a static amount modified by other modifiers? In other words, does leveling up *before* entering a nebula mean I'll be gaining fewer levels overall since the static XP is worth less at higher levels, or do I wind up benefiting because I get N levels of experience for beating the nebula?
