Like all modern games and apps, the games on your PS4 need to be updated occasionally as the developers fix bugs and make changes to the software.
Or, if you're in a hurry to get an update, you can force an update to happen manually.

1. From the game library, hover over the game you want to update.
2. Press the Options button on your controller. It should open the side menu.
3. Select "Check for Update."
4. If there's an update available, follow the instructions to install the update for that specific game.
