Transformers The Game PS3 - Autobot Mission 14 "Unfriendly Skies"

Continuing on. This is definitely one of the harder missions in the game. You start off by facing Starscream. Wait for him to land and lay the combos on him, dodge his blasts when he flies down the street in jet form. Soon Blackout joins the battle so its 2 on 1 now. Counter Blackout's attacks and lay the combos on him. When they both gang up on you, block and counter. If you need purple hearts, try to go for them while shooting Starscream and Blackout. They will stay still blocking and won't chase you. Try to focus on one of them, and take them out if you can because if you keep switching one of them will fly away and heal only to come back with full health. When both are destroyed, a cutscene will ensue and you will have to face Brawl next.
