Get the Drop on the Dropship
Look for the following drop ship, that is hovering near the 1st drop ship. If you take a sniper rifle and zoom in to the side doors, the targeter will turn red. You can take out enemies with one or two shots.
Flash Flood:
When you see the race called the Flood turn your flashlight on and point it at them. The large one will stop running and jumping so that they are easier to shoot.
