Futakoi Alternative: Koi to Shoujo to Machinegun is based on Japan's late night anime show. This Futakoi expands on the series for a story-line that follows six twin pairs instead of the show's main pair. Each scenario has two different routes, known as "Burn" and "Bud."
Gameplay is centered on interactive dialogue. The game makes use of what Marvelous calls the Reaction System, where key points in the story require that you press buttons in accordance with on-screen prompts. Also debuting is the Hustle System, where you make decisions about your path under the constraint of time.
