On July 5, we launched the experimental Recon Mission mode, which was created to give you the opportunity to play on pre-release prototypes of game locations and choose, in your opinion, the most successful of them.
Unfortunately, when working on the matchmaker for this mode, we didn’t take into account premium Tier VIII vehicles with preferential matchmaking, and these tanks are sent into battles with Tier X vehicles. The release of Recon Mission with the current matchmaker was a wrong decision and did not match your expectations. We apologize that the mode was launched in its current format without considering such an important aspect of the game, as well as for the lack of communication with you at its launch.
With this in mind, we have to discontinue the first Stage and take a break to make the necessary adjustments to the matchmaker, as well as conduct an additional mode check to rule out possible additional issues. The mode will be disabled according to the prime time schedule and you will have the opportunity to play in it today. In the future, the Recon Mission will be relaunched as soon as the necessary changes are made. Your game progress will be saved.
Stay tuned, Recon Mission will return after we improve it!
Thank you for your patience and understanding.
