Hawk
If you do not have anyone you can play with and you are forced to do this yourself, you can have a relatively easier time (and save ammunition) by simply using Hawk (the Assassin) to kill one or two enemies while cloaked. Then, retreat to regenerate energy. Repeat this until you need the really heavy firepower of your AI companions. Also while playing as Hawk, select your PowerBlade "PwrBld" in your inventory. Use her specialty (cloaking) and stab as many enemies as you can. One stab in an enemy kills them, and since Hawk runs very fast, you can take out many enemies without taking any damage.
