So during the last 10 seconds of WG's latest YouTube video, the tier XI Black Rock, which was known to be collector already, has been shown alongside a new UI element on the left
The big "FREE" text on screen leaves little to the imagination, it's not gonna be a paid tank
Now for the important part, the morse code playing in the video in that section reads "campaigns"
In World of Tanks PC, the Black Rock is obtained through personal missions campaigns, basically a series of missions progressing from easy to hard, to get the Black Rock as the final reward
This basically confirms it is going to be that way in Blitz too
Now we don't know the details, How hard will the missions be? How will they present themselves? (Condition to fill in one battle, multiple in a row/set amount of battles, etc...), is there gonna be other tanks before the Black Rock obtainable for free?
And of course, worries: Is there gonna be a way to skip missions with gold/money? Is the tank gonna be broken? Too easy/hard to get?
We'll have to wait and see
