Follow him and shoot while doing so. When he stops, attack him while jumping When he takes off again, repeat the strategy.
In the level where you chase Bumblebee as Starscraem, follow him until he transforms. To kill Bumblebee, jump around him in circles while shooting both guns (light and heavy). When he dies, Starscreem will have the Alspark and Barricade will attack. There are two ways to kill him. The first is to move left and right while shooting your heavy weapon. When Barricade transforms, jump off the building and destroy trees. This will restore your health. Climb back up and repeat the process. The other way is to transform and fly back and forward while shooting.
To defeat Jazz with Megatron, first climb the building behind you. Then, attack all the turrets but do not destroy them. When all five turrets are badly damaged, go to one of the corners and attack the furthest one. After you do this, Jazz will send Autobots to attack you. Do not worry about them; just go to the next turret and destroy it. Continue doing this until there are none remaining. After finishing this, a cinematic with Megatron chasing Jazz will appear. When the battle starts, attack Jazz with your heavy weapon. This will be difficult because Jazz is always moving. However, it will do a lot of damage. Also, if possible, do not go toward Jazz because he will just jump away. If your health gets too low, look for the entrance to the Sector 7 underground base. If you see it, go slightly into it then start running and transform. You must use the afterburner or Jazz will shoot you. If you manage to get to the bottom, destroy objects until you find health. Continue this until you have full health then go back out and attack Jazz again. If your health drops again, go back into the Sector 7 underground base and repeat the process.
Before you start the "Ratchet Retaliation" battle, make sure you are a helicopter. When you start, transform. Do not worry about the other Autobots; just fly back and forth attacking Ratchet. If you get low health, there is an area with tanks. Attack the tanks and most time they give you health.
After you destroy all the turrets,a little clip will start. After it you will begin to fight Jazz. Immediatly transform into vehicle form and fly away. Make shore you are always move up and down or left and right, because the turrets will fire at you. As you fly away look for a little building thing that leads underground. MAKE SURE YOU STAY IN VEHICLE FORM! Then fly down the into the buillding and continue flyind down until the clip of Jazz dyind starts. | [Sent by Kedesh
Go to any level with any vehicle form. The ability to climb walls must be unlocked. Star Scream is recommended. Go to the boundary of any level that is formed by a wall that you can climb. Once you find one, climb to the top. Once you reach the top, you will fall. The instant that happens, keep tapping X while holding Up so that you stay at the top of the wall, but keep loosening your climbing grip. Eventually your Transformer will look like it is going to get on or over the wall. Once this happens, do not move the D-pad. Your Decepticon will slowly float to the top of the level boundary. From here you can move your view and look around, but moving your character will cause you to fall to the ground.
While in Free Play, press start, go to "vehicle form" then select "confirm". From here you can just press B to go back to the game. You will now have full health and any wanted level will be gone.

When you begin the level Street Brawl you will begin to fight Ironide. Quickly run away from him and walk down any street. As you begin to walk around, look for a street that goes downhill. When you do find one, you will notice a gap between the street and a building. Lure Ironide to the area and then jump in the gap. After he jumps in, jump out quickly,and you will notice he can't get out. DO NOT GO TOO FAR AWAY, because if you do, he will jump out. Just stay in the area and throw cars poles and trees at him from a distance. ENJOY! | [Sent by Kedesh
