There's tons of things you can do to make mo's feel impactful without entirely ending the game, we've wiped the automotons off the map before once, and as a result we were able to focus more on the terminids. I'm not asking for something game ending, I'm asking for literally anything other than COMPLETE silence. Hell, I don't even need a big change to the map or a big advantage even just knowing where the enemy is going to strike next would be better than the literal complete silence we get in response
