Rainbow Six Siege, is getting its first major update as part of Operation Health, The title update will focus heavily on implementing 1-Step Matchmaking and Interactive Matchmaking.
This is a major technological improvement and so we will be using our new deployment process to ensure smooth delivery to all players. We have tested it on the TTS, and 2.2.1 will be deploying for PC on June 7th, 2017. The tentative date for Console deployment is June 20th, but please keep in mind that this may change depending on how the PC deployment goes.
The next update will be focused on issues with Hibana, Smoke grenade replication, aiming consistency, Alpha Pack Deployment, and other long-persisting issues.
If you enjoy the game as much as we do at TiX the update page is well worth a read.
