The update is also bringing a "visual and rendering overhaul" to four of the game's maps. Ensk, Live Oaks, Fisherman's Bay, and Steppes will all be getting a makeover. Finally, 8.4 will feature a brand-new tutorial designed to ease the new-player transition by providing training in tank controls, shooting mechanics, and combat tactics.
You can take a look at the new British tech tree after the break, then head to official WoT website for more information and a screenshot gallery.
