It’s always nice to get a free demo to try out a game before you buy or pre-order it, but you know what’s even nicer? Getting a free PS4 dynamic theme just for grabbing that demo.
If you grab the demo of The King of Fighters XIV in North America, you get the free “All the Fighters” dynamic theme directly added to your download list. You don’t even need to download it (even if I’m not sure why you wouldn’t). You can get the theme just by adding the demo to your account.
European players have it even easier. You don’t even need to get the demo, as the theme is available for free on its own, and you can find it here.
Incidentally, it’s a pretty good one, fully dynamic, with custom music and sound effects, as you can see below.
