Halo

You know another game I didn't like as a demo was Forza. Then the game came out and they must have fooled everyone as it was nothing like the demo. Might happen with Perfect Dark Zero. I saw a lot of debug kits and problems with some games. They were probably incomplete.

The Xbox 360 unit I trained on had an 80 gb hard drive. The debug units had larger hard drives, the standard units have 20gb hard drives, because they had actual games loaded on them.
