Rainbow Six Siege 4.2 Patch Notes Brings Back Previously Game-Breaking Operator

Rainbow Six Siege had a brief downtime on PC to implement a new patch with a number of fixes. The 4.2 update (aka Y4S4.2) is now live on PC, with a PS4 and Xbox One release date to be announced.

The main focus of the patch is the so-called “Clash Exploit,” a game-breaking bug that made the shielded operator overpowered. The exploit allowed players to fire her secondary weapon while her shield was still up, which made her almost unstoppable. Ubisoft disabled her temporarily while it worked out a fix, so with this patch live she’ll be playable again on all platforms.

The full patch notes also list a number of other fixes, including smaller-scale fixes to various operators, level design, and UI. You can check out the full patch notes below.

Meanwhile, the Siege team is undergoing some significant leadership changes, as game directors Xavier Marquis and Alexandre Remy recently announced they were stepping back to work on other projects. The new game director, Leroy Athanassoff, will be leading the project going forward. We already know Ubisoft plans to bring the game to PS5 and Xbox Series X. A separate team is currently working on the PvE spin-off Rainbow Six Quarantine.
