Halo on multiple platforms

Hi Loloweb,

Thanks for your post. If you are referring to the Master Chief Collection, there will be available cross-save features for this game.

"If you own on both the Xbox One and PC version however, you will be able to load up on either and your campaign progress will be unlocked appropriately on each platform as progress is made. Please note that mid-mission saves will not transfer between
PC and console builds as they are not compatible."

For information on how progress is saved on each platform and how they transfer, check out this article:

MCC Development Update - October 2019.

I hope this helps.

unfortunately no friend, you should be in the microsoft ecosystem

The only exclusive series we really have are Gears of War, Halo, Left 4 Dead, and thats about all thats left and more.

All the others have either died out or went multiple platform

Yes, as these are all separate platforms they are different versions of the game.

If you want to play on another platform after buying on one originally, you need to purchase the new platform's version of the game. However, in those cases you can sometimes find that multiple purchases are discounted; for instance, anyone who bought Halo:
Spartan Assault on Windows 8 or Windows Phone 8 before 15th December 2013 was offered the game on both Xbox 360 and Xbox One at a reduced price ($5).

Again: It is on MULTIPLE GAMES ON MULTIPLE PLATFORMS. Not one ubisoft game BUT ALL GAMES!
