Liking this so far
I have no idea what's happening so far (except for aliens attacking, and this being particularly painful at 3 in the morning) but this works. You haven't done a great big info dump, which I think would detract from your opening, I'd expect more details of what exactly this alien threat is in later chapters, and the start leaves me wanting to read on to find out more information on this. Instead, you've concentrated on getting right into Lux's head. Which works. Pretty obvious he doesn't like General Asshole (what's his REAL name again? Yeah, General Asshole is gonna stick). Can't say much more on one chapter, but good start so far.
