Restart your device. Sometimes a simple reboot can solve the problem as it clears any temporary glitches. Then check for game updates. If there are any available, install them as they often contain bug fixes. If it's a console game, also make sure your console's firmware is up - to - date.
As I mentioned before, if the problem persists, reinstall the game. Before reinstalling, make sure to back up any save files you have. Once reinstalled, see if the story mode is playable. If none of these work, it might be a more complex issue, and you may need to contact the game's support team for further assistance.
It could be that your system doesn't meet the game's minimum requirements. Or there might be a problem with the game's installation or server connectivity.
It could be that your internet connection is unstable, preventing the game from loading. Or, there might be some software conflicts on your device that are interfering.
The length of the Injustice story can vary depending on how you measure it. If you consider the comic series, it's quite extensive. But if you're talking about the video game or animated adaptations, it's shorter and more condensed.
I'm not exactly sure. It might vary depending on different editions and releases. You might want to check with comic bookstores or online comic platforms for the most accurate count.
Injustice 2's story is quite substantial. It has multiple chapters and missions that can take several hours to fully experience, especially if you take your time to soak in the details and side quests.
