The Duo and Squad modes use a party system with unique codes that let you easily join a team with another player. Here's how it works:
- Go to match settings and select Duo/Squad mode. (If you want to play with a randomly assigned partner(s), you can just select "fill" here or select "no fill" if you want to play alone in this mode).
- You can join a friend’s party or invite them to your own via party codes, which are the numbers next to "Party" in the upper left quarter of the screen. (Servers are shared between players on Steam and the Spellbreak launcher, so you can do this with anyone!)
- To easily share your code, click the "Invite" button, copy the code, and then give that code to the player you want to join your team.
- To use a party code, click the "Join" button and enter the code that was shared with you.
That's it! You should now be in a party with someone and you can play Duo/Squad mode together. Have fun!
Note: The default mode is currently set to Fill.
