Stop Soldiers form Coming out of Pill Boxes
In a level where you are equipped with a stasis gun,
go up to one of the pill boxes (the big rectangles
that look like elevators and have sirens on top.)
While a soldier is just coming out, but still in the
pill box, shoot the stasis gun at him or her. If the
soldier is inside the pill box and frozen this will
stop more soldiers from coming out for the rest of
the level.
