How do you send a message to all players in Halo Infinite's chat?

To send a message to all players in Halo Infinite's chat, one needs to access the game's text chat feature. This can be achieved by pressing the appropriate key or button that opens the chat interface during a multiplayer match—usually "Enter" on a keyboard for PC players, or by opening the communication menu with the controller for console players. Once the chat window is active, type the message and then send it to everyone by using the command associated with global chat, often designated by typing "/all" or "/global" before the message, depending on the platform and settings. After hitting send, the message will be broadcasted to all players currently engaged in the match. It's important to note that this functionality may be subject to change through game updates, so users should always check for any changes made to chat commands or the user interface.
