Rainbow Six Siege 1.88 Update Highlights

Rainbow Six Siege 1.88 update patch notes

Match Cancellation

The only new feature in the latest Rainbow Six Siege update is Match Cancellation. This comes into play when you begin a match and your team is smaller than your opposition’s. If you have teammates leaving before the first round begins, or the lobby is incomplete, you will be given the option to vote for Match Cancellation during the match’s prep phase. You will need a majority vote in favor to cancel a match. Thankfully, a canceled match won’t have any impact on your MMR.

If for whatever reason, you leave a match before the validation of a Match Cancellation, you will receive an abandon penalty. You need to wait for the match to be canceled before you leave. Don’t jump the gun if you’re worried about MMR.

Changes & Fixes

Plenty of balancing changes and more general fixes have been implemented thanks to the Y5S2.1 update. Melusi’s penalty zone has been reduced by around 33%, for example. You’ll be glad to hear, too, that Melusi’s Banshee is now quieter when in the first-person POV. The Banshee’s hitboxes are no longer larger than its model, too.

It’s not just Melusi that has been fixed and changed, however. Oryx should now be able to climb on the southern side of the hatch from B Secure Hallway on the Bank map, for example. Read through the full list of patch notes below for every fix and change.

Match Cancellation will go live with the Y5S2.1 update! We have tested it on the TS and as well as internally against a number of potential circumstances. However as it is a new feature, please let us know if you have any feedback or issues to report with Match Cancellation at r6fix.ubi.com.

  • Match Cancellation is a new feature that will allow players to cancel their current Ranked match under the condition that team sizes are unbalanced at the beginning of the match (eg: if players disconnect before the first round, or if a lobby is formed with less than 10 players). The Match Cancellation vote option will become available for the incomplete team during the prep phase and a majority vote will cancel the match. A canceled match will show as canceled and have no impact on MMR.
  • Abandon penalties are still in place and players who abandon an ongoing Ranked Match are still subject to escalating abandon sanctions.
  • If a match cancellation vote is triggered, leaving before the validation of the Match Cancellation vote will also result in an abandon penalty. Players should remain in the game until the Match Cancellation vote is validated and the game has been canceled.



  • Lowered the penalty zone by approximately 33%.
  • Reduced max range penalty radius from 6m to 4m (range in which penalty increases from 25% to 50% the closer you get to the gadget)
  • Reduced critical Range penalty radius from 3m to 2m (range in which penalty is 50%) See diagram below for how Banshee’s penalty ranges work.
