How To Download Warzone Without Modern Warfare

If you want to play Call of Duty: Warzone but don't own and aren't planning on purchasing Modern Warfare, you can expect an 83-101 GB download size, according to the official Activision blog. It's available as a standalone battle royale game on all available platforms, meaning PC, PS4, and Xbox One, and can be downloaded from associated first-party stores. Check out the download links below.

How To Download Warzone If You Own Modern Warfare

If you already own Modern Warfare and want to play Warzone, the update should start automatically upon launching the game. Depending on your platform, it's an 18-22 GB update. If the update doesn't automatically install, or you encounter other issues, try restarting your system. You'll see that Warzone has replaced, or "unlocked," the Classified panel in the main menu.

How Unified Progression Works In Warzone And Modern Warfare

In addition to being cross-play, Call of Duty: Warzone and Call of Duty: Modern Warfare feature a unified or shared progression system, meaning content earned across either game will transfer to the other, no matter which order you play them in. That means if you own Modern Warfare already and decide to hop into Warzone, your Operators, Battle Pass items, and other unlocks will be accessible in Warzone. If you don't own Modern Warfare and install Warzone as a standalone, then decide to pick up Modern Warfare at a later date, any progress you make in Warzone will carry over as well.

When Did Call Of Duty: Warzone Launch?

It became available to download first at 8 AM PT for Modern Warfare players, then at noon PT for players looking to install the standalone version.
