Telltale no longer seems to have included a code in their later physical releases, and the license for the season is included on the disc.

I'm sure Guardians is also a part of Telltale's 'Season Pass Disc' rollout, so it should work fine.ĮDIT: According to this reddit thread yes, buying a used disc will work. Haven't seen this for myself, since I've only bought Digital from Telltale, but I vaguely remember seeing a thread some 6 months ago about Minecraft Story Mode Season 2, and someone confirming their Disc grants the person the full season pass - even from a used copy (this was on Xbox). In that case, simply inserting the disc should automatically grant you the license for the season pass and let you also download the whole season, though it'll all only be playable with the disc inside. I've heard that many of Telltale's newer titles just have a 'Season Pass Disc' to get around the hassle of re-sold copies having already used/missing season pass codes. If not, then probably? You can't buy the game and its episodes off the store anymore, but I'm sure that if you redeem a code for it, it would have to grant you the license for that software, since it's still all in Sony's database, available to be re-installed at any time (as I did with GOTG just a few days ago). If there's an expiry date and the date has passed, then it will absolutely not work.
