Ubisoft has extended the Rainbow Six Siege closed beta through October 4.

The beta extension will be a way for not only fans of the Rainbow Six series to get more time to play the game, but it’ll also provide additional data and feedback from players over the next few days. In fact, Ubisoft is allowing those who participated in the beta the opportunity to invite their friends in. Anyone who play at least one match prior to 2:00PM ET on Sept. 29 will be sent an email with an immediate access code that can be shared with a friend.

The Rainbow Six Siege closed beta is one of the largest betas Ubisoft has ever performed and has learned a lot in the process. The publisher has identified a number areas that will provide long-term improvement for the game’s launch and also pushed out several updates that have helped ease things on a short-term basis.

Ubisoft shared some additional information regarding the beta, such as the average wait time for PvP matchmaking improving to 30-45 seconds and Terrorist Hunt having a 96% success rate per matchmaking attempt. The longer the closed beta runs, the more improvements Ubisoft can offer when Rainbow Six Siege is released on December 1.
