We can see almost all our stats and history on our Halo 5 service record here. Would you like to see anything added when Infinite launches? Personally, I would love to have heatmaps like Bungie used to provide with Halo 2/3 where we can see the areas where we kill and die on each map.
That could be something i would like, and it could be usefull for gameplans.
I would just like to see a full milestone list to return, it would basically include infinite along with other Halo games.
And maybe an in-game waypoint for Infinite. Much like the Xbox app but just in-game.
