I took a quick test on this and wow, just... WOW! Amazing mod. Really good, I love the fire and the smoke, the new ufo layouts, the breaching, everything. Chris really needs to make this the official go-to mod to be bundled with the game.
I need to make few fixes to the item graphics though, and maybe try to polish your xenopedia picture a bit too if you don't mind. Umm.. speaking of xenopedia: the breaching article still unlocks only after alien invasion. I suggest to put it in the /scripts/_basebuilt.lua.
EDIT: Uh, forget about the xenopedia stuff, I was blind.
