If it doesn't have a code on it, it's not the season pass.
The season pass (if you didn't buy it through Steam/XBLive/Playstation) will be a key code. YOu will enter that on the key unlocker in steam or in the respective console store (I am assuming since I don't play on consoles). If it's a valid key, it will add the season pass to your account.
Did a wee bit of a search. If http://www.highdefdigest.com/news/show/games/Review/Season_Pass/code/3/vault-dwellers-survival-guide-condensed-edition/Xbox_One/PS4/how-to-check-fallout-4-disc-boxes-for-the-perk-poster-plus-reversible-cover-season-pass-ad/27414
is what you got, then you didn't get the season pass. You just got a flier.
If thats the case, you just need to decide if you want to buy the pass now, or wait until its on sale. *shrugs* In either event I'd wait til the wasteland workshop lands so you have a better idea.
Don't worry, a lot of us fell for it as well as there were numerous threads about it at launch.
Haha just went and looked in my case. I think the thing confusing people is the " All access Granted " part.
Very misleading rofl......Good job Beth.
I suspect Bethesda didn't include free season passes for lols...
(that's Sony's job, cough...)
