Avalon Code (DS)

Avalon Code​ (アヴァロンコード Avaron Kodo?) is a fantasy action role-playing game for the Nintendo DS released in Japan on November 1, 2008 and on March 10, 2009 in North America. The game was created by Matrix Software. The plot, as well as the gameplay, revolves around the Book of Prophecy and the touch-sensitive lower screen of the DS. To record a person, monster, plant or weapon in its pages, the player performs a "Code Scan", which is done by hitting the target to be scanned with the Book itself. Each page shows the object's basic information, such as attack strength (for items), health points (for enemies) and personal likes, dislikes, and goals (for people).
In addition, everything that can be scanned has a Code - which is like DNA, but simpler. Its Code is in turn made up of many Codes, which are pieces of different shapes and sizes that fit into the object's grid somewhat like fitting pentominoes into a box. Creating different combinations of Codes, by adding and removing them, changes the object's title and sometimes has a major effect on the object. Changing titles to remove 'defective' Codes, as well as creating 'new' items, is a facet of gameplay used in many sidequests and occasionally within the story.
