In the distant future, human beings invented space warps, which allowed space travel to long distances. On board the space ship Agamemnon , they started an intergalactic journey. But an accident happened, and the humans were thrown into a parallel universe. Years have passed until they have adapted themselves to the different civilization. This parallel world, composed of three huge continents, is called Babel. Zell is a teenage boy, an orphan who lives in a post-apocalyptic world riding his bike, together with his friend Alice, who is like a big sister to him. One day they meet a mysterious girl named Sefia who seems to be on an important mission. Their struggle against evil begins at that moment...
Babel is a Japanese-style RPG set in a futuristic world. Zell and his party travel around the world, visiting large cities and encountering many randomly appearing enemies. During the turn-based battles, each character can use a variety of attacks with different weapons, as well as special techniques. The combat window shows animated moves of the party members. Unlike in most role-playing games, characters do not receive experience points from defeating enemies; only money is gained. The characters level up according to the player's progress in the narrative.
