As soon as I finished the campaign, I was back on the drugs like "Oh, there's a squad to rescue right there in walking distance!" and "Oh, another FOB to capture!". I get that it's Far Cry-esque, but I really enjoy that "One more thing" game mechanic.
I'm adding explanation videos to my YouTube "Watch Later" list because I've played every Halo game, but that lore will get away from you, quickly.
Somebody here unlock the Legendary secret ending (there's gotta be one), because I know I'll never see it, outside of YT.
