When you reach "Lies of the Past: Checkpoint 4", you will ascend in an elevator. Exiting 
the elevator, you will see a replica of the Moon's surface, a model of the U.S. space suit,
and a shuttle the United States used to reach the Moon. This is in reference to the Moon 
Landing Conspiracy, claiming that the U.S. never actually reached the Moon, and faked the
landing to beat the Russians in the space race. The conspiracy was heavily debated, but 
ultimately rejected by the majority of opinions. Today, only a few people still claim the
Moon landing was a hoax.
