Wargaming.net has announced that the World of Tanks v7.3 patch has been successfully deployed. The patch largely centers around the substitutions and additions to the Soviet tank heavy tanks line into the game.

Leading the way through the redesigned tech tree, the update moves the IS-4 tank into tier 10 of its own heavyweight line with KV-4 and ST-I. The KV-3 has moved from tier 6 to tier 7, and freed the slot for another newcomer, T-150.

New gameplay elements introduced in the 7.3 include the addition of a new battle arena, the South Coast, and the first map set in Asia, the Dragon's Ridge.
