Pretty cool, this will help the game maintain a larger online population, I played it for a while in the past and enjoyed it. Details below and how you can tell if you are playing against a Nintendo Switch player:
"We’re thrilled to announce that for the first time ever, Xbox One Paladins players will be able to face off against gamers on another platform.
Crossplay multiplayer is coming to Paladins on June 12, putting Xbox One and Nintendo Switch owners on the same servers! This will make the pool of Paladins players even larger, resulting in better and more competitive matches for all Xbox One players.
You’ll always know when you’re playing with Xbox One gamers — just look for the Xbox One logos next to their Gamertags. And if you don’t want to crossplay with Nintendo Switch owners for some reason, don’t worry; you’ll be able to turn off crossplay in the settings menu."
