You say cheese... but Commander difficulty is incredibly punishing. I think I would be taking immense casualties without extensive smoke use. UFO #1 started with a whopping 15 aliens! I can't even imagine how crowded late game Battleships or Dreadnaughts will become at this difficulty. Can't wait to find out. =D
Also, there is a bug with the HEVY Smoke Launcher. When you reload it, it will sometimes CTD Crash to Desktop. Very annoying, especially if I'm running 4 or more HEVY Smokers.
