Want to turn your PS3 games into PS4 games? It's not hard. You just have to follow these steps.

Today PlayStation Access released a cute video about the upgrade process, which might not be available for every cross-gen game, but has been confirmed for some, like Watch Dogs and Assassin's Creed IV, both announced for current- and next-gen systems. You can buy both games on PS3, then pay a little extra ($10) to play them on PS4 too.

The video is British, keep in mind: you obviously won't have to pay in pounds if you live in the U.S.

And via Sony, here's a step-by-step text walkthrough:
