Warzone is now part of Modern Warfare 4
Season 1 is when Warzone is fully integrated with Modern Warfare 4. All 33 launch weapons from Modern Warfare 4 can be used in Warzone along with the Season 1 additions, and progression, Operators and Apex attachments carry across modes.
- Hajin: a new Battle Royale map.
- Zodiac: a new map for Resurgence.
- Verdansk: the classic Battle Royale map is expected to return to the rotation later in the season.
Activision has said a full roadmap is still to come, so expect more events and limited-time modes during the season.
Halloween pre-season modes
Before Season 1, Activision added Halloween modes such as Infected and Possession to keep players busy. Check in-game for what is still available.
Tips to get started
- Update the game and make sure you have enough storage, since seasonal updates are large.
- Check which Battle Pass tiers unlock the CSG-35 and the Cronen Osprey, then plan your first challenges around them.
- Try the new Warzone maps in a trio or quad before ranked play to learn their layouts.
- Use the catch-up mechanic if you are starting late, so you do not miss rewards.
Details are based on Activision’s Season 1 announcements and early coverage at the time of writing. Check the official Call of Duty blog for the latest patch notes.
