The game is broken. Seems to start with behind the scenes type stuff that should be an unlockable after completion, and then throws us into what feels like the halfway point and we're just supposed to know what's happening.

I scoured the city for 5 hours trying to make progress, and couldn't find a single mission trigger. It's a shame this was free, because I can't call it a cynical cash-in, but it definitely is that in spirit. Fans of the films, please avoid.
