When using agent nine on the missions through the air
vent. Duck down nearly all the time. If behind any of
the tall objects you can stand up but don't show
yourself, coming out start crawling again. When facing
the rhynocs under manholes it's best to jump down when
there underground and when they pop up suck them in.
This helps loads when coming back to the air vent to
talk to sparks and give him the key half. Sent in by Lynn Stewart
