"The EYE Brings the Battle to Life.
The unique combination of the PlayStation 3 system, the PlayStation Eye and innovative CyberCode technology evolves the trading card genre into a revolutionary gaming experience. Collect hundreds of cards and create a deck that comes to life as you strategically battle head-to-head, against the computer or against an arena of online players.
The game included a starter deck and a random booster of physical cards. Additional cards could be acquired via pre-built decks or booster purchases. Two expansion releases added additional cards, requiring purchase of a software expansion via PSN.
The Eye of Judgment is a hybrid paper and electronic collectible card game which can be played using the PlayStation 3 game console, supported by the PlayStation Eye camera peripheral. It is one of the first games to use the peripheral, which is bundled with the game, along with a fixed Starter Deck and 1 booster pack. The trading cards are encrypted along their edges with a CyberCode matrix code. The game can also be played without the use of the Playstation 3 system, as a stand-alone card game. However this will cut out many unique graphics and require a person to keep track of numerous scores normally tracked by a computer - mana gain/loss, health bars, element advantages, field terrain changes, etc.
Players take turns playing creatures or spell cards from a 30-card deck in order to control a majority (5 fields) of the 9 total fields on the playing mat which is laid out in a 3x3 grid. Other than controlling a majority of fields, players can also win if their opponent runs out of cards to play. Creatures' overall effectiveness is determined by their Hit Points and Attack Score as well as any special abilities they may possess. Five elements divide the game's units: Water, Fire, Earth, Wood, and Biolith. The playing grid fields have a top and bottom side and each side is affiliated with one of the five elements. Creatures placed on friendly elements receive HP bonuses while creatures placed on an opposite element (a Fire creature placed on a Water field) suffer a loss of Hit Points, so unit placement is important.
