Call of Duty: Warzone is a free-to-play battle royale shooter, and to get the best out of it, you need the best ping possible. Ping refers to the amount of time it takes your PC or console to communicate with the server. In an ideal world, you’ll connect to a nearby server with a low ping and plenty of players, but in reality, connections can be way less consistent. Using a VPN with Warzone can help you get on a server with plenty of other players and a consistent connection, even if it’s not the closest one to you.
