Hi, Would really appreciate help on this.

I have completed all of Transformers - The Game for the PC, well, all of what I could see achievable, but my profile shows that only 97.0% of the game is completed, and I also still have 1 of the bonus videos not unlocked !

I have collected all cubes, all icons, completed all challenges, skills, side missions, main missions cybertron, the whole lot !

What else do I need to do to complete to 100% ???
