Konami has announced in their latest financial result that the Metal Gear series has now surpassed 49.2 million copies in worldwide lifetime sales, as of March 2016.
In the Pachislot & Pachinko Machines business, we intend to release new pachislot machines, SEVEN’S BEAT, in collaboration with beatmania, a music genre game from the Konami Group, and METAL GEAR SOLID SNAKE EATER, which was derived from the ultra large-scale video game title METAL GEAR series (surpassed 49.2 million copies sold worldwide as of end of March 2016). This is the first model loaded on the next-generation cabinet BIGBOSS, featuring the industry’s first full-HD surface 32-inch LCD, and equipped with a 124 GB large-capacity ROM for the LCD.
This means the series has done quite well in the past year: at the end of March of 2015 sales were at 41.2 million, meaning an increase of 8 million since then. This can probably be largely attributed to the succes of Metal Gear Solid V: The Phantom Pain.
