I activated a Dorito code on Waypoint since it seems there’s nowhere in the game’s UI to punch in codes, and it tells me this:
Success!
Your code was successfully redeemed! Please check your in-game inventory for your items.
Cool! So what did I redeem? The website doesn’t tell me, and to be honest I would rather not scour through the dozens of cores, nameplates, emblems, weapons, vehicles, and permutations therein to find out what my new gear is.
