The PlayStation 3 version was released, on the Japanese PlayStation Store, on September 25, 2008, &s a free download and followed the same pay-per-item model as its PC counterparts.

The story of the game is based in a land called Eden, a reference to the ancient garden in the Bible. The game lore states that long ago, there was no difference between the human world and heaven, that every corner was filled with happiness... that is, until something unexpected happened. The Archangel Lucifer apparently fell in love with a girl who was already in love with another angel. Soon enough, jealousy consumed Lucifer until he lost his mind, transmuting the girl into dew and the angel into starlight. He knew that he would soon be punished by God, so he gathered a rebellious army of angels to attempt to overthrow the reign of good.

Unsurprisingly, he and his army lost and were forever expelled into hell. Ever since then, he had been plotting his revenge, establishing a demon training camp to gather his forces for his strike against heaven. Even worse, he believes now is the time to initiate his plan. It is here that the player comes in...

There are many different types of jobs in Angels Online which are divided into three major groups or systems; the Combat System, the Magic System, and the Production System.. Combat System: The Combat System composes of the job classes that deal physical damage, whether up-close or from afar. They wear heavy armor referred to in the game as "Garment", the sole exception being the Archer class which uses leather armor referred to in the game as "Mantle".

Every player starts in the Angel Lyceum, a college to train Little Angels (the players) to become Angel Protectors to guard Eden against Lucifer (requirement). Once the player finishes the tutorial, they are teleported to the campus of the Lyceum where they can accumulate student credits on campus by doing lessons (composed of either defeating a certain number of a monster or collecting/manufacturing a certain amount of an item). The student credit`s primary purpose is to determine whether a student can now graduate or attend the Top Student Training. When a player graduates they become an Angel Protector and choose a faction and city.
