Looks like Apex Legends Mobile is shaking things up this weekend. For a limited time, Ranked mode will support active legend perks, allowing players to utilize these unlockable abilities in a competitive setting.
The perk system will only be live in Ranked from July 22-24. It’s a very tight window–it seems like Respawn is doing this more to test out how perks might affect Ranked, rather than introduce a true limited-time mode.
Perks are exclusive to Apex Legends Mobile–they are not present in the console/PC game. You unlock perks for a legend by repeatedly playing as said legend, providing a means of further specializing how a given character performs.
