Eye of Judgment is a turn-based card battle game that utilizes the PlayStation Eye camera peripheral and a 3x3 rectangular table mat with real trading cards. The camera not only recognizes the cards, but also the position and rotation. The mat represents a battlefield where players can summon creatures and cast spells. The story takes place in a fictional world shaped by The Source. Mankind's vain pursuits lead to the construction of Bioliths, devices of iron used to help defeat the gods. After a long war, Jeano, the son of The Source, turns all the devices to rust. Eventually, four sages find four different nations: fire, water, earth, and wood. There is a time of peace, until a mechanical fortress appears in the sky and the Biolith surprise attack wipes out three of the four nations. The remaining one, wood, receives a message to send a lone wizard to Cape Edgeworth with a single chance to defeat the Biolith Castle.
The game can be played through single-player, head-to-head modes, or online. Through the camera, movement is tracked and creatures seem to come to life on the screen. Each turn, players move a card, rotate it, or change its position. Abilities change according to the position, and placing a card face-up summons a creature. While attacking, the screen shifts to a battle mode where spells can be used. The center area is always Biolith, while the others are randomly divided over the four different elements, influencing abilities and providing bonuses or weaknesses to certain creatures. Actions are performed through mana, received at the beginning of a turn or through certain cards. The first player to capture five areas of the field wins.
Neat tricks with the camera include a profile mode where players can hold a card in front of the camera to view information and interact with the creature.
The base game comes with 30 summoning and four function cards, and a booster pack with eight additional summoning cards. Additional packs can be bought separately.
