Ground Zeroes is a stealth video game developed by Kojima Productions and published by Konami. It was released in 2014 as the prologue to Metal Gear Solid V: The Phantom Pain. The game features an open-world environment, allowing players to explore and complete missions at their own pace. One of the standout aspects of Ground Zeroes is its emphasis on stealth and strategy. Players must use a variety of tools and techniques to navigate through the game's environments undetected, including sneaking, crawling, and using distractions to avoid detection. The game also features a day-night cycle, which adds an extra layer of challenge as players must complete missions within a certain time frame. The game's story is set in 2014 and follows the events of Metal Gear Solid V: The Phantom Pain. It takes place before the main game and serves as a prequel, providing context for the world and characters that will be featured in the main game. Ground Zeroes also features a variety of side missions and collectibles, which add replayability to the game. These missions can be completed in any order, allowing players to explore different parts of the game's environment and complete objectives at their own pace. The game's soundtrack is another standout feature. The main theme, composed by Ludovico Einaudi, captures the game's sense of melancholy and introspection. The death metal version of the theme, titled "Death Metal Gear - Ground Up Zeroes," adds a darker edge to the game's soundtrack, fitting with its emphasis on stealth and strategy. Overall, Ground Zeroes is a well-crafted stealth video game that provides a solid foundation for the world of Metal Gear Solid V: The Phantom Pain. Its emphasis on stealth and strategy, combined with its open-world environment and variety of side missions, make it an engaging and challenging experience.
