Will I be able to quickly jump from one player’s perspective to another? Yes. You can easily jump from observing one player to another by clicking on the appropriate portrait on the left or right side. Alternatively, each player can be selected from the drop down menu in the bottom left corner. |
(Sorry if this is in the wrong spot, but the spectator mode guys should be able to pass this along to the right web people)
