After escaping from the train, the duo fights through the rubble of dark, deserted, underground parking garages and tunnels, searching for a way to head up to the surface of the city. If this dosent work? Turn the wheel on the right side of the grate-door until the gap is wide enough to get the white car through, use your Gravity Gun to dump the wreck downstairs, and, at last, block the final antlion spawning pit. Remember to Gravity-blast the antlions so Alyx can take them out for you. Watch out especially for grenades in these tight quarters.
