Front Mission is set in a futuristic world where the development of giant robots (Wanzers) has made warfare between nations a common occurrence. Political and governance conflicts have significant impacts on both politics and society. The game often raises questions about ethics, the use of technology in warfare, and the global consequences of conflicts. The story is divided into several chapters, each told from the perspective of different characters, including both soldiers fighting for the mission of governments or organizations, as well as those who oppose corrupt regimes.  The game uses a turn-based tactical system, where players must plan and move strategically in the battlefield to control Wanzers (giant robots) and attack enemies. Positioning, weapon selection, and utilizing each character's skills are crucial elements in winning battles.
