World of Tanks: Blitz players are challenged to become one of the first 60,000 to complete a special 8-stage battle to earn a free premium tank called the IS-Defender.
To complete each stage of the battle mission, a player must collect the requisite number of tokens. Tokens are gathered by earning XP in battle and completing the stages of the battle mission. Those who earn the IS-3 Defender will also receive a special camouflage for the vehicle.
The players who do not complete all the stages of the battle mission do not have to worry either—as they will be rewarded with credits and XP for the stages they did complete. From the fourth stage, tankers will also earn increasing amount of Premium Account time with every subsequent stage completed. Only the quickest tankers will be able to reap the benefits of this one-of-a-kind tank, so they’d better get their fingers at the ready.
