yep, I'm also stumped on that one. Found one solution that haf me win in 49 hours, but that wasn't good enough.
Also, I have a solution that works in 47 hours but the game won't let it count
It's simple: just send any amount of drillers to the enemy queen's location and kill her. But as it doesn't end the scenario I guess that's more or less a bug...
OK, here's what I figured so far: your enemy is 9 points off and you 16. So you gotta bump up your production by 2 within the first day to reach 200. Can't get it done fast enough, though...
