So, I've recently asked my parents to pre-order Danganronpa 2x2's Collector Edition on the official shop of the company. The bundle includes a bunch of stuff which are useless to know here, but, it also includes a Steam Key. Will I be able to use the key before the game's official release, or will i need to wait for the game to release to use it, or even, will I receive my package WHEN the game releases? I've been really confused about that, so I'll be glad to have some help !

Thanks for anyone helping me!
