Patch 4.4.0 - December 3, 2019

New Content & Features

General Tweaks and Improvements

Player Comfort

Gadget Trajectory Asset Destruction

We're in the process of updating breakable props across all our maps to be more structured in how they are destroyed when they are in the pathway of gadget projectiles and missiles. The goal is to make destruction of various elements across maps more coherent for players. This first iteration should allow projectiles to break fragile props that would otherwise block their path (ex: Grenades, C4, etc.).

Game Health

Gadget Code Optimization

With the new season, we’ve improved the coding logic for a number of primary and secondary gadgets to protect against potential regressions and widen their capacity for future complexity.
These backend changes will not impact your experience using the gadgets.

Casual Renamed to Quick Match

Casual is now called Quick Match. Same game mode, new name.

Quick Match + Newcomer Role Swap

Quick Match (previously Casual) and Newcomer playlists will adopt the AA-DD role swap. Similar to Ranked, players will swap roles once a match.

Playlist Guides

You will now be able to find all the information you need about a game mode in the new Playlist Guides! Newcomer, Quick Match (previously casual) and Unranked game modes will now have Playlist Guides similar to the Ranked guides.

Operator Voice Overs

The Operator voices for Hibana and Mira have been re-recorded with new voice actors. We are thankful to the voice actors that we worked with up to this point, but with the expansion of our Universe content, we needed to make adjustments to our talent line up to ensure consistency.
