Defend the hill | Infinity Halo 4 Guide

Go to the furthest cannon from console and door (screen). Start firing at enemies but don't move a cannon. When you eliminate the last one, return to console and take Cortana.
When the door opens, return for one cannon. Get inside a tunnel, where you see a Knight at its end. Prepare for a big number of enemies there. Try to stay in tunnel as long as possible. Firstly, focus on Watchers. Just until you enter the cave, you find a path on right leading to a shelf with good vision.
When support will be dropping, retreat to tunnel or behind some cover. When the area is secured, enter Pelican, which will land in the cave.
