General Tweaks and Improvements

Game Balancing

Breaching Charges

  • Deployment animation is much faster.
  • Damage on Attacker's side is reduced from 150 to 50.
  • Damage area of effect on Defender side is increased.
  • Lethal damage area of effect on Defender side is reduced.
We wanted to make the breach charge safer and more comfortable for the attackers to use.

Crouch and Lean Spam

We have identified a way to have a substantial impact on the viability of spamming crouch and lean commands. Currently, player animations allow players to snap from left to right lean, as well as crouching, without going through the full animation for that action. We will deploy a fix that prevents this from being exploitable in Y4S1.
We will continue to monitor the situation following the deployment of this fix, and take necessary steps should it not have the desired outcome.

Player Comfort

Advanced Deployment

We will be testing a switch to Advanced Gadget Deployment for all players. We feel very strongly that Advanced Gadget Deployment is the proper way to play Rainbow Six Siege, as it allows for more control over your Operator, as well as increased fluidity.
As always, we will be monitoring feedback on the Test Server, so please let us know what you think about this feature!

Game Health

Shield Operator Rotation

When Shield Operators turn in place, there is a slight delay before the shield and upper body snap to align with the legs. This can cause a mismatch between first and third person perspectives. We are deploying a change that will make this left and right motion more fluid, and ensure that first and third person perspectives are aligned.

MMR Rollback

With the launch of Y4S1, we will be activating the Match Making and Rating (MMR) Roll Back feature. When a cheater is banned, this feature will roll back MMR gains and losses for all players from matches that the banned cheater participated in for that Season. The system will not grant you MMR beyond your max MMR for the current Season.
More details can be found in the MMR Roll Back article, here.
