Look at this beast! 😛
The mysterious and spooky tank which is hidden in the fog is made up from:
Turret: KV-4
Hull: Tiger P
Mantlet: T34 (or T29 or T30 (the same tank, virtually))
Cannon: Most likely T32.
While little is known about him, there are rumors that it will be a premium, which will be on sale for Halloween. These are only rumors and speculation.
