The door was officially deactivated, even when a team grabbed the artifact. I'm not sure why, bit it was. :wink:
Good idea, though. It would have made for some VERY interesting temple designs. Could you imagine a design that forces the player up through the Crypt, up into the Observatory, down to Medusa's Lair, then into the Rock Quarry, then into the Laser Light Room and on through the rest of the temple? That would be a very tricky design!
