Rainbow Six Siege Y5S2.1 update nerfs Melusi, Ace, and Hibana - and adds a cool new feature

Melusi, Ace, and Hibana are the latest Rainbow Six Siege operators to be nerfed - check out the full patch notes here.

Melusi loadout Rainbow Six Siege

Ubisoft is in the process of rolling out a new Rainbow Six Siege update, the biggest since the release of Operation Steel Wave a couple of weeks ago. The Y5S2.1 patch will nerf Hibana, Ace, and Melusi, and it will be live later today, June 30.

In addition, the update introduces a cool new feature named match cancellation. This allows an incomplete team to vote to abandon ranked matches, absolving them of an abandon penalty and meaning they will see no impact on their matchmaking ranking. However, Ubisoft warns this option will only be available in matches that begin with uneven teams, and that if you leave before the vote has passed, you’ll still be hit with abandon sanctions.

Melusi’s nerf is the most significant in the Y5S2.1 patch: her Banshee device now slows enemies from a shorter range than before and makes a slightly quieter sound, reducing its effectiveness.

Ace and Hibana, meanwhile, see very similar nerfs to one another: their respective X-Kairos and Selma devices will no longer destroy gadgets on the other sides of walls, as their explosion damage cannot now pass through walls. Other than that, the update, which should be completed on June 30 at around 07:20 PT / 10:20 ET / 15:20 BST following 20 minutes of server downtime, contains a bunch of bug fixes. You can read the full list below, via Ubisoft.

Rainbow Six Siege Y5S2.1 update patch notes


Match Cancellation

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.
