Steel Wave UBISOFT

Rainbow Six Siege has finally entered the second season of its fifth year and Ubisoft has made a lot of additional changes for the launch of the live servers and for the 2.1 patch which will follow it soon. Melusi will lose her shield for a C4 on the live servers and Ubisoft also intends to fix the possibility of destroying bandit batteries through reinforcements.

Some major bug fixes and UI changes were made to the game, including changes to the shop and minor changes to cosmetics. ACS12's slug shotgun has a bug where you don’t deal damage from any distance above 40 meters. There were also some visual changes made to the texture of the weapon sight, where the color was too dark.

Rainbow Six Siege Y5S2 Patch Notes

You can find the patch notes below:


Y5S2.1 update

During the Steel Wave test server period, we received a number of feedback requests for balancing tweaks to the new Operators. After evaluating feedback from players, and data from the TS, we plan to make a few balancing changes to the new operators with the 2.1 patch. The changes will not go into effect until the Y5S2.1 update.

Melusi - Coming in Y5S2.1

  • Lowering the penalty zone by approximately 33%.
  • Lowering the sound of Banshee effect in first person POV.

Ace & Hibana - Coming in Y5S2.1

  • Remove the possibility of destroying Bandit's Batteries through reinforcements, by placing the charges on the floor.


  • Replace her deployable shield with C4.

After re–evaluating a number of current game–meta and gameplay factors, we made the decision to swap out Melusi's deployable shields for C4 to prevent putting extra pressure on attackers and specific attacker utility.


  • Increased the damage from 41 to 59. Increased ADS Speed.
  • Increase the ACS12 RPM to 300 RPM.

Buff to the ACS12's damage to make it a bit more viable than it is currently. ADS speed should also now match other weapons of the same category. Furthermore, on release, the ACS12 had 300RPM, and it was lowered by a later balancing change. With this change alongside the change to slugs, the 300 RPM should not have issues with destruction.



  • Now has an ACOG. This is where all the lost ACOGs went.


  • French localized audio for Ace and Melusi will be available in FR at launch. RU localizations are still unavailable.


  • Attachment system updates allow for attachment skins and simpler loadout balancing.


Adjustment to metal detector SFX and activation on Bank, Kanal + Border.

  • Now plays a short 3–sec alarm before stopping.
  • Only one alarm can be played at a time.
  • No cooldown on the alarm trigger.

This fixes an issue where alarm cooldowns meant that players could cross metal detector barriers multiple times without an alarm sounding (if it was already triggered previously and on cooldown).



  • FIXED – ACS12's slugs deal no damage from distances greater than 40m.
  • FIXED – M4 reload animation and audio are slightly out of sync.
  • FIXED – AK12 reload animation and audio are out of sync.
  • FIXED – FPS drops when debris flies next to players.
  • FIXED – Bulletproof Camera casing still deploys after canceling when crouching.
  • FIXED – Deployable shields (and Goyo’s Vulcan) have pick–up priority over other throwable gadgets. Gadgets should be able to be picked up in the order of most recently deployed.


  • FIXED – Various Menu UI improvements.
  • FIXED – Various minor cosmetic and shop UI fixes.
  • FIXED – Various minor menu fixes and improvements.
  • FIXED – Various cosmetic fixes to charms, uniforms, headgears.
  • FIXED – Empty player cards visible in spectator mode if all observation tools are destroyed and player joins–in–progress.
  • FIXED – Floating drones in support and caster mode.
  • FIXED – Outlines of objectives and some gadgets are sometimes highlighted while in support mode after dying.
  • FIXED – Various caster/spectator HUD improvements and updates. Increased legibility of the player states on player cards.
  • FIXED – Visual replication issues from 3rd person POV for operators exiting rappel from a rooftop.
  • FIXED – Texture for black weapon attachment skin is darker on holographic/laser sights.
