The Firing Range from Call of Duty: Advanced Warfare is back in Call of Duty: WWII. Players have the ability to access the Firing Range directly in the Divisions customization menu.
The Firing Range allows players to test out their loadouts before entering the match. In the final game, the Firing Range is also part of the new Headquarters Social Space. In HQ, you will actually be able to see all other players at the range at the same time. The E3 build did not have HQ feature active, so we were not able to see other players.
