Can't finish optional objective #9 - visit the hippies and kill them with the rocket...
I have tried guiding rocket through them, blowing rocket in the middle of them, going up myself and doing above (ensuring tthat they are all dead twice), but no success.
Survived day 12
I won't try day 13. Lost an elevator because man keeps shooting after I stop clicking. Now I can buy 2 empty eevators or one with weapons. Don't know which is better.
