Konami has provided updates for the total sales figures of its Metal Gear series: it's 51.3 million copies since 1987 – a total that includes numbers registered until late March last year. The previous update, dating from March 2016, spoke instead of 49.6 million units sold overall. In the year that separates the two numbers and saw the series of Hideo Kojima sell 1.7 million additional copies there was theRelease of Metal Gear Solid V: The Definitive Experience. The next game of the series, the first without the famous author, will be the spin-off Metal Gear Survive, which we will see at E3. Source: Metal Gear Informer
