As previously announced, we are currently experiencing technical issues connecting to the Internet at our main development center in Minsk, Belarus. Taking this into account, we are postponing the launch of Act V of World of Tanks’s 10th Anniversary indefinitely. This decision was made to ensure that we can provide you with quality support and the best possible experience during the event. The price reduction for Tier VI-VIII Premium vehicles has also been postponed and will not occur on the previously announced date. The prices for these tanks will be changed later upon further notice. We truly appreciate your patience and understanding.
