Game rooms help you make a room for you and two friends to play together as a team.
In order to create a new room, you need to select the event of your choice and then tap the box that says "Create new room".
Once you do so, simply tell your friends about the ‘room code’ to join your room which is located at the top right of the screen!
Tap on the character avatar to cycle through your available characters. Be aware that two identical characters can not be used in game room teams. However, you may be matched against players who have selected the same brawler who have not made a game room.
