Beat Droidekas:  To kill a Droideka easily, stand as close as you can to it, and directly in front of it (between its gun arms). It cannot shoot you. Kill it with melee attacks to save ammunition. Note: If there is more than one Droideka, stand so that you are in line with as many of them as possible so that the others cannot see you.

Beat Greivous' Guard:  Use your EMP grenades and concentrate your men's fire on them. Once they are being shocked by the EMP, throw Thermal Detonators to deal extra damage. You should also use your DC-17's anti-armor attachment.

Beat SBDs:  Throw two electric grenades and fire a quick bust from the DC-17. This should shut them down or put them on the ground.

To defeat a Super Battle Droid, run up to him while he is shooting at you. Then melee him and back up before he can hit you. While he is swinging his arm, fire at him with your blaster. After he melees, he will resume shooting at you. Repeat the process until he is destroyed. If there are two SBDs, concentrate your team's fire on him.

Walking turrets:  In the Wookie level hanger, enter a gun turret. Use the Left Analog-stick to slowly move the turret around the hanger. You can even take it off the edge of the platform. You cannot fall off, even when you get out -- you will return to the platform.

Number Infinity:  Note: This glitch happens rarely, and may only happen once. In the level Final Strike, after you get Sev (07) to his turret, get to the next Spider Droid room. Then, kill your squad, shut down, and reload. Note: Save before the spider. You should start with Fixer missing and Scorch's will possibly be 6200. After finding Fixer, continue the game. The adviser might keep saying something like, "Delta Lead, revive your squad!". Ignore this and keep going until you find a Geonosian above a dead clone. Kill the Geonosian and revive the clone. He will either float up to the roof or just stand there and breathe. You have now found Number Infinity.
