There is another passage, though it was block by the falling debris.
As player reaches the passageway, Regina will look around the fallen debris before a pack of compy arrive. Assuming Regina's role, player can head toward the side passage to find a door entry toward the materials room.
An elevator at the end of the passage leads to the large size elevator area.
