Play anything you want in Third Person.
Interact changes the side the camera is on.
Interact + Primary Fire zooms in the camera up to a maximum.
Interact + Secondary Fire zooms out the camera up to a maximum.
Widowmaker and Ashe can still use their scopes as they normally would.

By default the gamemode is set to Deathmatch, but you can adjust the lobby settings to whatever you want.
