Operator Changes

General Tweaks & Improvements

Game Balancing

Win/Loss Conditions

We have changed the Win and Loss conditions for our various game modes, effectively removing the possibility for a round to end in a Draw.
  • If the last player on each team dies at the same time, the following win conditions come into effect:


  • (Not planted) Defenders Win – Bomb Protected (same as if timer runs out)
  • (Planted) Attackers Win – Bomb defused


  • Defenders Win – Container protected (same as timer runs out)


  • Defenders Win – Timer Expired

Player Comfort

Ranked Guide

See a snapshot of the current Ranked season with the new Ranked Guide. Upon entering the guide, players will be able to look at the current season's rewards, map pool, and directly enter matchmaking from this page. Each player's personal Ranked stats and where they stand amongst others can easily be accessed. Explore the main rules of Ranked (with the newly added Pick & Ban) before jumping into the game, and see which maps have been added, removed, or reworked in the Ranked map pool.

Operator Selection Screen

The Operator selection screen has been improved to increase readability and show more information at a glance. See all weapons and gadgets available for an Operator, get a gauge of their difficulty rating, or choose to randomize your Operator selection in this revamped screen.

Ambient Audio Tuning

We have taken steps to reduce the impact ambient noise can have on your gameplay, specifically on Bank and Border.


  • The team on the helicopter has changed their search pattern to cover a wider area, forcing them to circle the objective from further away. This has also reduced the amount of noise from the helicopter for the Operators on the ground.


  • We spoke with the management of the Bank, and stressed the importance of being mindful of their water usage. As such, they have turned off the sprinklers in the Basement. They were not able to provide an ETA for when they would remove the water from the floor.
  • The fire alarm is now a more intermittent alert than a constant sound.
  • The circling police helicopter has moved a bit further out to give our Operators more space, and reduce the noise that the helicopter is making.
  • Ventilation boxes also received an upgrade, and now make less noise.

Soft MMR Reset

We are adjusting how MMR is managed when a new Season of Ranked is released in order to improve the matchmaking experience at the beginning of a Season. In the past, we reset all players to a 2500 MMR at the beginning of the Season. Moving forward, we will reset MMR between the “middle” (2500 MMR) and your rank from the previous Season, with extremes above 3500 and below 1500 clamped to those respective values. This will also apply to placement matches. This change will also lead to players reaching their “true skill” faster; players that should be Diamond will reach Diamond faster. We understand that some players, particularly those at the extreme high end of Diamond, would like more of` a “grind” implemented for attaining the higher ranks. We have heard these concerns and are working on how to provide that type of experience for those who want it in the future.

Menu Loading Times

We have adjusted how we manage loading items in the menu. This has had the result of reducing the delay between selecting different weapons attachments and other items, leading to a smoother flow overall.

Observation Tools Feedback

We are adjusting the indicator light colors on Defender and Attacker Observation tools to be more consistent. Moving forward, Observation tools controlled by Defenders will be blue, and those controlled by Attackers will be yellow. Additionally, Observation Tools that are under the effects of Vigil or Nøkk are now white. Ultimately, our goal is to ensure players can easily recognize a friendly, hacked, or enemy observation tool.

The following gadgets and tools have had their light colors changed to follow this design:

HUD Visibility

Player's HUD will now remain visible when Flashed/Stunned. The HUD is a source of information for the player, not for the Operator they are controlling, and as such, the HUD info should always remain visible.
