The game won’t install past 1 gb if I’m lucky. Pretty much tried everything, and the only solution I can think of is buying the game (again) digitally that I already played $100 for on release.
Do you have enough space on your hard drive? Does your internet service provider (ISP) have a download limit?
Try this -
- Put the disc in.
- Pause or cancel its install.
- Go to the game store
- Find Halo 5
- Pick the install option from there
- Your game will now install via network instead of the disc.
Let me know if this helps.
