World of Tanks has spent the last several months gearing up for its comprehensive Update 1.0. Developer Wargaming has now confirmed the long-serving combat vehicle MMO will receive a new graphics engine and overhauled maps come March, 2018. 

Courtesy of an "advanced" CORE graphics engine, more than 25 of WoT's maps stand to be redesigned in a bid to "meet modern graphical standards", so says the developer in a statement.
