Left Alive is a survival third-person shooter developed by Square Enix for the PlayStation 4 and PC. The title is a spin-off to the Front Mission franchise and takes place in the year 2127, placing it between Front Mission 5 and Front Mission Evolved. The game follows three protagonists who are trapped in a Russian city called Novo Slava during "The One Day Incident," a conflict that marks the beginning of a larger war. Caught in the middle of this battle, the protagonists must find a way to survive through stealth, setting traps, crafting materials, hijacking enemy mechs (known as Wanzers), and direct combat. How the player reaches their objective is open-ended but depending on the methods used and the path taken by the player, the story will be affected in a number of ways.
