Due to the ever-popular "legal and licensing" reasons, we are required to disable all of the Fallout gift codes that were generated for free during the 48-hour Fallout giveaway. I know that this will probably inconvenience some of you guys, and you've got our apologies for that. Unfortunately a bunch of people were re-selling the codes and this got noticed; as is often the case, a few bad apples can spoil the fun for the rest of us.
If you actually purchased a Fallout giftcode in the past with real cash money, you should be fine to redeem if; if for some reason that doesn't work, please contact Support and they'll--as always--set you right.
Well that's a pile of suck. I grabbed a load, but it was just to give to my friends who didn't actually grab it themselves during the 48 hours.
It's also really annoying that you didn't tell us in a more direct way. I sent some off today without knowing they'd been cancelled, so thanks for that.
