Warzone is free on PC, and the official download runs through either Battle.net or Steam — pick your launcher, install the desktop app or client, and let the 116 GB download begin.
That 116 GB figure is the first thing to know. Warzone is a big game, and the download fails more often from a full drive than from anything technical. The second thing to know is that the download path depends on which launcher you choose — Battle.net requires its desktop app and a linked Activision account, while Steam works like any other game in your library. Both are free and official. One bad source will try to sell you a “setup” file from a fake download page — the only legitimate sources are the two storefronts below.
Which Launcher Should You Use?
The answer is whichever you already have installed — your existing library is the fastest path. Battle.net and Steam both deliver the same game, same updates, same servers. If you have neither, Battle.net is slightly simpler for new accounts because it manages the Activision account link inside its own sign-up flow. Steam requires a separate Activision account link after install, which catches some players off guard.
Download Warzone via Battle.net (Simple Path)
Battle.net is the traditional PC home for Call of Duty titles, and the flow is built around its desktop app. You cannot install the game from the website alone — the app handles the actual download.
- Go to the Call of Duty: Warzone page on Battle.net and click Install or Download.
- The site will prompt you to download the Battle.net desktop app. Install it if you do not already have it.
- Open the app and sign in with your Battle.net account, or create one if you are new.
- The app will then ask you to link or sign in with an Activision account. This is mandatory — the game will not launch without it.
- Once both accounts are linked, find Call of Duty: Warzone in the app’s game library and click Install.
- Choose your install location — an SSD is strongly recommended, and you need 116 GB free.
- The download begins. Wait for completion, then launch from the app.
Download Warzone via Steam (Easy If You Already Use It)
Steam users have an even shorter path: the game lives in your library immediately after you add it. The Steam page is listed as Call of Duty®: Warzone™.
- Visit the Call of Duty: Warzone Steam page and click Play Game (or Add to Library if the button says that).
- It will now appear in your Steam library. Click Install on the game’s library page.
- Choose your drive and confirm the 116 GB install size.
- Once downloaded, launch the game. On first launch, Steam will prompt you to sign in to or create an Activision account — the same step Battle.net handles before downloading.
Success cue after first launch: you will see the Warzone main menu with the season pass and play buttons. If you see a “sign in” screen instead, your Activision account link did not carry over — restart the game or link it manually on the Activision website.
Warzone PC System Requirements — Can Your PC Run It?
Activision groups requirements into three tiers. The SSD and 116 GB of space are non-negotiable at every level — this game will not run from a mechanical hard drive.
| Tier | CPU | GPU | RAM | OS |
|---|---|---|---|---|
| Minimum | Ryzen 5 1400 or Core i5-6600 | RX 470 / GTX 970 / GTX 1660 / RTX 3050 | 8 GB | Windows 10 64-bit (latest update) |
| Recommended | Ryzen 5 1600X or Core i7-6700K | RX 6600 XT / RTX 3060 / Intel Arc B580 | 12 GB | Windows 11 64-bit (latest update) |
| Competitive | Ryzen 5 5600X or Core i7-10700K | RX 9070 XT / RTX 4080 / RTX 5070 | 16 GB | Windows 11 64-bit (latest update) |
One detail that surprises most people: the minimum tier actually lists an RTX 3050 as acceptable, which is a modern card that still meets the bar. If you are running an older build of Windows 10 that has not been updated recently, the game may refuse to launch — keep the OS fully patched.
The single most common mistake is ignoring the SSD requirement. Players with 1 TB hard drives and 130 GB free routinely fail installation because the game writes to the disk in a pattern a spinning drive cannot sustain. If the installer stalls or crashes at “writing files,” move the install target to an SSD.
Two Mistakes That Waste Your Time
The first is downloading from a non-official source. Searching “Warzone download free PC” returns pages that bundle fake installers. Only the Call of Duty store, Battle.net, and Steam are legitimate entry points — there is no separate installer file to download from a news site.
The second is confusing the launcher steps. Battle.net requires the desktop app before the game download will start. Steam adds the game to your library but does not begin the 116 GB download until you click Install. Neither platform auto-starts the download after you visit the product page — you must initiate it through the launcher or client.
What Happens After the Download — First-Time Setup
Once the download finishes and you launch the game for the first time, expect these three things:
- A shader optimization pass — this can take 5–15 minutes depending on your GPU. The game is unplayable until it finishes.
- A prompt to link your Activision account. On Battle.net this was already done, on Steam it happens at first launch.
- A settings screen asking about graphics quality. The game defaults to a recommended preset based on your hardware — you can tune it later.
After that, you are in the main lobby. The download is complete, the accounts are linked, and Warzone is ready to play at no cost.
