Metal Gear Solid: Master Collection Vol. 1 is releasing next month, on October 24th, and Japanese fans can get their hands on a variety of pre-order bonuses, depending on the store they make their purchase. On the official website, Konami lists the different items you can obtain through each retailer, including their own Konami Style Store.
The offer applies to the PS5 and Switch versions of the game, the two versions that will be available in physical format in Japan. The title will be presented at Tokyo Game Show later this month ahead of its release.
