However, it will not be secure for much longer as the game will shut down shortly, and everything relating to the title will be wiped and no longer accessible. According to Activision, Warzone Caldera will be formally closed down on September 21, 2024; after that, you will not be able to access the game anymore.
Activision makes a completely unnecessary sequel to a free-to-play battle royale game, and then shuts down the first game soon after. None of your time, progress, and money spent on the first game are transferred for zero good reason. It's all just arbitrarily deleted.
