Turret

Turrets fire two lasers in your direction at regular intervals. In order to get rid of them, you have to constantly dodge their fire. Luckily for you, if you are out of range, they go away.

A neat trick is to jump on top of the Turret -- this will make it go down. Press the "X" key rapidly and get rid of the other distractions, (Battle Droids, Commander Battle Droids , Super Battle Droids , Clones , Clone Commanders , etc.), before leaping off and finishing the Turret.
