Halo EVA; Level 4:
WARNING! The plans you stole was a fake and now Green Horn Covenant are on their way to attack your base and you people. Everyone... Including your partner has evacuated. It was a everyman for himself thing. You search the hangar sections for a operational Pelican. You find one at the far end of the base. You reach there through the underground passageway. You find out there are demolition scouts that are searching for the final pelican. You must reach it before the Elites do!
