Start out as a clone trooper. Run outside to the balcony overlooking the glowing chamber thing. It is likely that the droids will be controlling the command post so get ready. There will probably be a ton of Super Battle Droids and some Droidekas. Use thermal detonaters and your rifle as neccesary. Keep an eye out for spawning droids as you are capturing the CP. After securing the CP, get full health and ammo and run down the corridor into the main hall and simply start blasting. Happy blasting!
