Theory time. What if you can only sync a blaster if you buy a specialty blaster from the Villain-Con gift shop. It’s paired to the app exactly same way a Power-Up Band. And would be the only way to track your scores and be in the leaderboard. Your device would be paired once and then automatically updates score after each ride same as SNW attractions, but also means no extra time is needed to spend pairing a device to an app while about to board a moving pathway.
Also explains why graphic in app shows a replica of Vector’s blaster. Perhaps you can buy one based on every villain from all movies, which explains why their silhouettes are on the poster but not the actual ride (which only features the Vicious 6)?
But that’s just a theory.
