Hack is a 3D Anime/role-playing game for the Sony PlayStation released in 2002. It is produced by Bandai.
The lead character is Kite, a young boy who becomes a follower of a new online role-playing game called The World. For a while, Kite and his school friend Orca have a great time in its fantasy world, until an attack by an undocumented monster somehow leaves Orca in a coma in the real world.
Subsequently, Kite becomes an even more dedicated to the game, hoping enough exploration will allow him to find a cure for his friend.
