Septerra is a world which is composed of “layers” - continents that spin around the planet center. In the center is the Core, a kind of a living computer. According to the legends, the Creator of Septerra left there a precious Gift - an artifact that grants the one who possesses it legendary powers. Septerra is controlled by the Chosen, who live at the top of the world, consuming massive amounts of energy and throwing the “waste” down, to lower levels. Maya, a “junk scavenger” who lives among those wastes and earns the living collecting junk, unexpectedly comes into contact with the Chosen. It appears that their goal is to reach the legendary Gift. Maya and her friends decide to face the Chosen, and ultimately discover the true history of the planet.
Despite its Western origins, Septerra Core is a Japanese-style role-playing game. The game’s visual design is close to Japanese anime, and the emphasis of the game is on a character-driven linear narrative with simple role-playing mechanics. The game’s story evolves across the seven worlds of Septerra, each with its own distinct style, including post-apocalyptic, semi-medieval, futuristic, etc. In the first half of the game the player-controlled party explores these worlds on foot, accessing towns and other areas from an overworld. Later the player gains a ship that allows fast transportation to any world, including previously inaccessible areas.
Combat is turn-based and takes place against enemies who either visibly wander around or appear at pre-set locations in hostile areas. There are no enemies on the world map. The action bar of each character is divided into three segments and is gradually filled. Opting for either fast and weak or strong and slow attacks, the player must select a character in real time, stopping the bar and pausing combat. Magic spells are usually awarded after completing plot events and may be combined with each other by two or three characters to create new ones. The player is for the most part free to form a party of three active combatants from a larger cast.
