Has anyone else managed to complete this mission? Its the one where you play as Bumblebee and have to destroy a series of turrets. I can successfully clear the first 4 turrets in the first 4 minutes but the mission then gives you 3 mins to clear 4 more turrets that are high up on the buildings out of reach. No matter what I try I cannot jump up high enough to reach these turrets!! Anyone know what im doing wrong or how to get up to the rooftop level of all 4 turret buildings? Thanks.
