Players spend most of their time trying to evade enemies and create improvised weapons when stealth fails or is not an option. Left Alive is a primarily stealth-based third-person shooter, with survival game elements as well.

Some characters were conceived prior to the game's planning, and many changes to their appearances and ages occurred as the story was solidified. Originally conceived as a strategy game, it gained more action elements as development proceeded, and ultimately became the first survival game in the Front Mission series. Set in the Front Mission series, the story follows several individuals trying to survive amidst a surprise invasion of one country into another, along the way helping civilians to safety and to stop destruction and damage by mechanized war machines.
