Spectator Mode is the method by which players can observe matches rather than participating in them. There are three scenarios in which spectator mode is used.
If a player is waiting to respawn and has skipped the killcam, they will be allowed to spectate their teammates until they respawn. In all gamemodes except Elimination, the spectator is locked in a third-person perspective and cannot rotate the camera manually.
If a player joins a group that is already playing a match, that player will be allowed to spectate the team until someone leaves. The spectator will be able to switch between first-person and third-person perspectives.
When setting up a Custom Game, up to 12 players may be put onto the spectator team. These spectators may be assigned teams or be left neutral, allowing them to spectate anyone and to have their own, free-roaming camera. Neutral spectators will also be able to see every player's hero, health, and ultimate charge at once.
