Earlier today a glitch was discovered that let’s you get Neon Chrome for the PlayStation 4/Vita for free. Those interested just need to do the following steps to get it for free.
Start by going to the PlayStation Store and purchase the Neon Chrome demo. Once you have the demo on your account, look at the Neon Chrome page and it should be listed for free. If so, purchase it and download your free game.
While it’s quite likely this will be quickly fixed and Sony will disable copies obtained like this, you’re still welcome to try.
