This may seem really stupid but I can't find the special features. It says on the back cover:
On the disc for the first time ever:
All 5 episodes of Back to the Future: The Game
Complete Behind the Scenes video series
Full production art gallery
Video reel with hours of audio commentary (includes never before seen content)
Now obviously I can find the episodes but I can't find the other stuff. Do I have to complete all the episodes to see the special features? Can anyone help?
