Dying Light developer Techland has released the game's opening cinematic into the wild.
The opening cinematic doesn't show any gameplay footage or anything like that. Instead, it's focused on explaining the backstory and setting of the game, and so it's not really spoilerific.
If you're looking for something more elaborate, why not have a look at the story trailer?
Dying Light is out January 27 for PC, PlayStation 4 and Xbox One.
