As one plays through the game they can develop more weapons and tools with the enemies they capture. While not every one has to be used, the sheer fact that their is so much choice makes for a lot of fun experimenting.

As the player levels up gear so will the AI, who are programmed to constantly keep the player on their toes. Being that the whole game is designed to allow the player tackle any level in a multitude of ways, seeing the AI always react differently makes for an original experience every time something is tackled.

Metal Gear Solid V gives players multiple choices on how to approach a mission or clear an outpost.

For example, the player can choose to use stealth and cunning in order to complete their mission and kill only when it's absolutely necessary, or they can get in guns blazing and kill every single enemy soldier sometimes even sniping each one of them from afar or calling the helicopter for air support.

This gives a special flavor to the gameplay and doesn't let it get stale for a long time since it leaves the choice on how to play to the player, without penalizing them for not completing a mission by using stealth (as other previous MGS used to do).

Throughout the story of the game, the player will be trying to rebuild their private military which was lost in the epilogue of the previous title in the MGS series.

Other than building their "Mother Base" which is an ever-evolving giant structure which serves as a base of operations for the player and other NPCs which help the player, players can also recruit enemy soldiers to increase the size of their mercenary company. These soldiers can help based on their area of expertise to either work on developing new projects or be dispatched around the world to complete missions and earn in-game money.
