Cush

Think it's been mentioned a few times in this thread, but it seems like there are too many aliens packed into those light scouts. My troops are advancing incredibly fast. After a month or so I had at least 1 Major, couple Captains and the rest were LT's. (this is also due to the high number of light scouts that appear)

After researching Alien Biology it told me that Stun Weapons and Toxin Grenades were available for research but they are not showing up as options
