In this mission you are Bumblebee and Blackout is chasing you. You have to get to each checkpoint within the time limit. You have twenty seconds to get to the first checkpoint and each checkpoint gives you two-to-five seconds. There will be military vehicles blocking incorrect paths. Eventually there will be cars in the way. If you destroy one head-on they will hurt. The way around this is to hit them with less than half of your front (about where a headlight is). Make sure you don't run out of time.
