A new video from Playstation Access showcases how to upgrade PS3 games into PS4 games. Sounds crazy? I assure you, it's actually quite simple.

Basically, when you purchase a participating PS3 game, inside the case will be a voucher. That voucher contains an access code that allows you to repurchase the game for your PS4 at a discounted price. The game will always held on your PSN account so make sure to redeem the voucher before it expires and you'll be able to play that game at any point in the future when you decide to get a PS4. Don't discard the disc, though, because it acts as a key, allowing you to play the PS4 version of it.

What if you purchase the PS3 game digitally? Then the digital copy will come with an access code, allowing you to purchase and play the PS4 version, only without needing the PS3 version as a key.

You can watch the entire step-by-step process in the video below.
