This level is a very good example of the deadliness of chaingun drones. The best way to complete the level is to try to avoid exposure to them. Flip the starting switches, then cross the bottom, and use the launchpad on the left side to launch yourself into the upper left part of the map. Watch out for the chaingun fire. Flip the switches, then drop down to the lower left corner, and activate the terminal. Cross the bottom again, then use the launchpad to launch yourself into the upper right section. Climb the crosshair, and use the upper launchpad to launch yourself into the exit, and beat the level.
