Sudeki is a 2004 action role-playing game developed by Climax Studios. It was originally released for Xbox by Microsoft Game Studios. A Microsoft Windows port was released in Europe by Zoo Digital Publishing in 2005, and worldwide via Steam and GOG.com in 2014 by Climax. Set on the splintered world of Sudeki, divided into the twin planets Illumina and Akloria, the storyline follows four characters chosen by the god Tetsu to prevent the return of the dark god Haigou and reform Sudeki. Gameplay follows the four protagonists as they explore various environments, with different characters fighting enemies using third-person melee or first-person shooter combat.

Shadow play, also known as shadow puppetry, is an ancient form of storytelling and entertainment which uses flat articulated cut-out figures which are held between a source of light and a translucent screen or scrim. The cut-out shapes of the puppets sometimes include translucent color or other types of detailing. Various effects can be achieved by moving both the puppets and the light source. A talented puppeteer can make the figures appear to walk, dance, fight, nod and laugh.
