Battle.net Free Games — When Paid Games Go Free, Temporarily
Most games on Battle.net cost money — World of Warcraft needs a subscription, Diablo 4 is a full-price purchase, Call of Duty isn't cheap either. But all of them go free temporarily, through promotions that have no public schedule. Call of Duty's Free Access weekends are the biggest and most frequent — here's exactly how they work and the simplest way to never miss one.
🎮 This article is about temporary free access — not Blizzard's permanently free games
A handful of Blizzard titles (Overwatch, Hearthstone, Diablo Immortal, Warcraft Rumble) are free forever, with full detail in our Blizzard free games guide. This article is different — it's about normally-paid games on Battle.net that go free for limited windows, especially Call of Duty.
Battle.net's Paid Games — And When They Go Free
These are normally paid, but each has a history of temporary free-access promotions:
Call of Duty Free Access Weekends — How They Work
This is the most common, most frequent type of free promotion on Battle.net. When a paid Call of Duty title (Modern Warfare, Black Ops, etc.) launches a new content season, Activision regularly opens up Free Access — multiplayer and Zombies modes become playable by anyone, for free, for a few days, with no purchase required.
| ✅ What's included
Full multiplayer maps and modes, plus Zombies in most recent titles. The single-player campaign is typically excluded. |
⏰ How long it lasts
Usually 4–5 days, tied to a season launch. The exact window varies and is announced shortly beforehand. |
📅 How often
No fixed monthly schedule, but it's happened with most major season launches across multiple Call of Duty titles in recent years. |
Progress and unlocks earned during a Free Access weekend usually carry over if you buy the full game afterwards, though it's worth checking the specific terms each time, since this can vary by title.
What About WoW and Diablo 4?
Both World of Warcraft and Diablo 4 also run occasional free-access promotions — WoW's "Free Game Time" for returning players, and Diablo 4's free trial weekends. Since these are Blizzard's own promotions with their own pattern and history, we cover them in full in our Blizzard free games guide. The short version: just like Call of Duty, neither follows a fixed schedule.
