This mission is crows nest.

Turn on a few skulls that you feel comfortable playing with then either play on normal if you are by yourself.
An excellent combo is a plasma pistol overcharge then switch to the battle rifle. Then kill off any grunts.
When evacuating the base a swarm of drones will fly over you, kill them all with the grunts quickly. Just finish the level in time for the 3x bonus.
