Instructions
Begin the chapter called "Exterminator." Keep an eye on the health of Bumblebee, which is located under his picture in the upper-right corner of the screen. Continue clearing a path around Bumblebee to keep him from taking significant damage.
Press the "Square" button to fire your weapon at the Energon drones when they're far away, and press "Square" to punch the drones when they're in striking range. Press "Down" on the directional pad to lock onto a target before firing.
Defeat 100 Energon drones. No timer exists for this level, so your only concern is keeping Bumblebee alive as you defeat the drones. Pinpoint the location of Energon drones by checking for the red dots on the map indicating their presence.
