At some point, the season ticket devices will become free. I know josh said this somewhere, I don’t know where the exact post is though, but… you’re gonna have to wait like 5 seasons.
If you want someone to give them to you though, you can make a request at the wix
For NPCs, you can place down sentries, customize their skin, and put them on the same team as everyone else so they won’t try to k!ll you. Or place down a barrier device and make it invisible so they can’t sh0ot through it.
If you want an NPC then just do what Hdangerzones said, place down an invisible button under it connected to some text above the sentry that will appear when the button is pressed.
