The offer for day 9 in the Advent Calendar brings one of the Berlin Quartet vehicles—the powerful ISU-122S. The combination of astonishing alpha damage and rate of fire makes this destroyer a major threat on the battlefield! Being one of the Berlin tanks, the ISU comes of course with a highly trained crew by default. The package also contains a Garage Slot and a reasonable amount of gold for other expenses.

p.s. This offer is available only for 24h
