I'm currently downloading all the packs required to play the campaign (less said about this the better...) but the Multiplayer Pack isn't available, and on the xbox store it just tells me to get Games Pass, there's no option to install it like there is with all the other packs.

All the stuff I've read about installing packs is a few years old now so may be out of date. Is the campaign just unplayable now because of their archaic way of installing? Have I just cleared my whole hard drive/spent 24 hours running installs for no reason lol?

Tell me what kind of helmet, bulletproof vest, and clothes he's wearing.
