Footage of an early Perfect Dark Zero build that runs on pre-release (beta) Xbox 360
 

never played PD0, so I dunno what's different. what I can say is the bloom looks like it hasn't been fine-tuned. Sure hope it didn't ship like that. The motion blur looks good though.

I didn't watch all of it but it pretty much looks the same as the final version.
Two things though:

1. Most of the missions preview pictures are different, however they still portray locations from the game's final version.
2. Mission 0 skips the tutorial and immediately kicks off the second half of the level (yet the "Objective complete" notice shows up at the very beginning, indicating that either the tutorial was skippable or they hadn't added it yet but they had already planned to).
