Brightis is a 3D action role-playing game set in a medieval fantasy world. After the Barge Empire disturbs ancient ruins while excavating magical Elements, a sealed gate is opened and demons are released into the world. The player controls Al Ted, a sword-wielding mercenary and the sole survivor of a destroyed military unit, who must explore dangerous ruins and recover four Global Elements capable of sealing the gate again. Gameplay combines real-time melee combat, guarding, magic, exploration, character skills, and light-based dungeon puzzles.
