Wargaming announced the Iron Brotherhood content update for the free-to-play World of Tanks: Xbox 360 Edition. The free update is available now and adds five new Soviet-built tanks and a new map to the game, offering plenty of impetus to jump back in and get blasting. In the Iron Brotherhood update, you'll get the T-150, KV-3, KV-4, STI and IS-4 Soviet heavy tanks, with armour thick enough to withstand a brutal beating and guns that can deliver a barrage of massive damage to enemies. The new 'South Coast' is also included, offering "new strategic opportunities and terrain to explore". Check out the new Soviet tanks in the new World of Tanks: Xbox 360 Edition Iron Brotherhood update screens below. Spoiler
