When the new Season Pass for the Animals Assemble Season in MARVEL SNAP was unveiled, a few players noticed that the Level 47 Mystery Variant that's usually on the Free track was instead exclusive to the Premium Pass. This was obviously a source of consternation for free-to-play players, but the developers at Second Dinner were quick to respond:

Quote From Second Dinner

Some of you have noticed the Season Pass Mystery Variant moved to the paid track from the free one.

This is a bug and NOT the experience we want for @MARVELSNAP players.

As an apology, we'll be gifting everyone a FREE Mystery Variant via the inbox.

Stay tuned for more details!

With the PC build still in Early Access, PC players will need to get on their phone (or use an emulator) to access the Inbox. As of posting, the free Mystery Variant has not gone out; we will update this post once they start showing up in players' Inboxes.
