Man, Infinite’s campaign was such a disappointment. Halo to me was always about the big set pieces and new locations. Infinite had 2 locations essentially the whole game, not to mention the non story that happens mostly off screen. It’s too bad because the grapple hook was one of the best additions to Halo since Bungie but you don’t have anything fun to actually play with it.
RAID is redundancy. It saves your data if a or two drive fail, but does not help you if the entire RAID system dies (power surge, fire, water damage). Generally if it is on the same system it is not a backup.
