Mickey and Dutch are finally re-united, but just after getting out of one fight, they head straight back into another. Marines and Police officers are trying to protect the ONI Alpha Site. Mickey and Dutch must prime charges on the bridge leading inside the base. After doing that, they head inside, but are pushed back to the building itself. Once there they find more charges and find out the whole place will be blown sky high to protect the information stored there. After fight waves of Covenant, they head to the roof for evac.
