"If players want to communicate something else to their teammates, they can bring up the ping wheel. Players can choose between four options-Quiet, Watch, Help, and Go. The wheel can be brought up by holding up on the D-pad or holding the "Alt" button on keyboards. Once brought up, players will need to select the ping they want to use and then release."
