With Operation Ember Rise coming to the live servers, we wanted to shed some light on the Casual Playlist changes coming at the launch of Year 4 Season 3, and around the 3.3 patch for PC and Console.
We currently have a total of 22 maps; 14 in the Ranked Playlist and 20 playable in Casual. As announced on the Seasonal Patch Notes, we will implement a new Casual map pool rotation. This Playlist will now have 14 maps instead of the current 20. Moving forward we will rotate 4 maps in and out of the playlist with each rotation.
With the release of Operation Ember Rise, this is what the Casual map pool will look like:
In a mid-season patch, we will replace Skyscraper, Hereford, Fortress, and Chalet, with House, Plane, Favela, and Tower. We will post updates on social media channels before it reaches the live servers.
Bartlett University and Theme Park will not be playable during Season 3. The latter will be receiving a rework with the release of Y4S4 and won’t be available throughout this season.
Our goal is to give players the ability to familiarize themselves with a more curated selection of maps. We are also aiming to make the playlist more dynamic and enjoyable.
