Diving through the gates and battling the beasts in Solo Leveling Arise can be lonely. A multiplayer mode where you can explore the dungeons with friends would make the experience much more enjoyable, as you can complete boss battles more quickly.
NETMARBLE IS IN TROUBLE!!! HUGE OPPOSITION & LAWSUIT! (Solo Leveling Arise)
Unfortunately, things aren't looking so great on the team-up front. That's perhaps not the biggest surprise for a game called Solo Leveling.
No, Solo Leveling Arise is not multiplayer and does not have co-op features. However, there are global leaderboards for various modes, including Power of Destruction, where you can compare scores with other players.
The only thing you can change here is that you can customize your profile so that anyone viewing the leaderboards will see a welcome message and your character's avatar.
