Halo 5 campaign doesn't save

Halo 5 won’t save the campaign no checkpoints or manual saves etc do I do

I would try the following steps and see if any of them help. If the first doesn’t work, move on to the second and see if you have any better luck:

  • Restart your Xbox - Hard reset your Xbox - power off completely, remove power cable for a minute, reattach and then switch back on - Uninstall and reinstall Halo 5 - If you are running Halo 5 from an external drive, try installing on your internal drive
