Operation Chimera

Two new Operators join Team Rainbow to help contain a mysterious parasite infection that hit a small town in New Mexico. To safeguard the perimeter, Six selected the most qualified biohazard specialists in the world: Lion and Finka. From France and Russia respectively, the hot zone Operators Lion and Finka are veterans of numerous conflicts involving biochemical threats. They join Team Rainbow to create a CBRN Threat unit, which will provide tactical gear and expertise to quell biological hazards. Read full details about Rainbow Six Siege Operation Chimera.

  • 2 new operators
  • 3 Player Coop Gameplay
  • 5 Types of infected hostiles
  • 3 New Coop Levels
  • Outbreak Collection
  • Chimera Weapon Skins

Operator Balancing


  • Increased recoil: The recoil will be harder to control. It will pull harder on the camera, and the maximum amount of kick (max diamond size) is bigger.
  • Damage reduced: The damage is lowered from 28 to 23, to better take the high rate of fire into account
  • Scorpion Evo 3 A1 damage updates: Our objective is that she remains efficient at taking fights at short distances when getting pushed by attackers, but is at a clear disadvantage when taking medium to long range fights versus assault rifles with ACOGs.
  • Loadout changes: A deployable shield will replace her impact grenades. As many of you identified, she was too good at doing all the roaming work by herself: preparing rotations, being warned by Concussion mines, and of course killing with her SMG. This loadout change will force her to rely on teammates for rotation holes, or to pick the shotgun if she wants to do them herself.


  • Impact grenades will replace Kapkan’s barbed wires. He already has a lot to do in preparation phase to set his traps up – having impact grenades for faster rotations is a better fit for his playstyle.


Blitz has been working out, and will now be a 2 speed / 2 armor operator.

General Tweaks And Improvements

Game Health

Rotation desync for DNBO players: In some instances, the server was rejecting shots to players in a DBNO (Down But Not Out) state. The reason for this was a desynchronization with the game server. After downing an enemy, you could see him rotating in one direction from your point of view, while on the server, their movement was completely different, and that is why some of your shots to DBNO targets would not register. We have addressed this desync and your shots should now land properly and accurately on downed enemies.

Player Comfort

  • Changes to ammo update timings: All weapons ammo updates are now slightly faster. They have been rationalized according to their animation. This should make reloading a lot more comfortable.
  • Interrupting tactical reload with going to ADS: You can now interrupt a tactical reload (reloading with a round in still in the chamber) with aiming down the sights. Before you could only do it with sprint, but now if you are reloading and someone surprises you and you want to shoot, all you have to do is go to ADS and fire instantly with your remaining ammunition.
  • Reload resume points: Missing reload resume points have been added to all weapons reloads. When you interrupt a full reload, if you have done certain steps (ie. Discarding the empty magazine) you won’t do that step again when resuming the reload animation.
  • Raw Input on PC: We will be implementing a new input method on PC. This raw input option reads mouse/keyboard values directly from the hardware, without any post-processing. This may slightly improve the responsiveness of the mouse/keyboard during heavy load. This option can be found under Controls > Raw Input.

Playlist Changes

  • Rainbow Six Siege update 1.45 removing Bartlett University from the Casual Playlist and adding Yacht back. Ranked Playlist remains unchanged.

Game Balancing

  • Deployable shield walking: You can no longer walk on deployable shields. At any instant that an operator is considered walking on the shield, it will collapse on itself (be destroyed) and the shield is refunded in the inventory of the defender that placed it. That will prevent players from utilizing exploits by walking on a shield.
  • Melee hit validation: Rainbow Six Siege 1.45 applied some tweaks and improvements that should make melee attacks much more reliable.
