is an iPod tactical role-playing game developed and published by Square Enix worldwide.A new version entitled Song Summoner: The Unsung Heroes - Encore was announced for the iOS at the 2009 Tokyo Game Show. This game expands on the original game with new Tune Troopers and a reworked storyline twice the size of the first. The game was released on App Store on December 2.GameplaySong Summoner is similar to other Square Enix tactical games, but unique in that troops, called Tune Troopers, are generated from songs on the user's iPod. There are 50 characters that can be generated, each of which falls into one of five job classes: Soldier, Mage, Archer, Knight, and Monk. Most of the Troopers and their skills are named or modeled after songs, albums and musicians from both Japanese and Western music.Each Trooper is given a rank of bronze, silver, gold or platinum as well as a secondary letter ranking based on its statistics in relation to its rank. The higher a Trooper's rank, the fewer times it can be deployed; however, further deployments, called rewinds, can be bought. When the player plays a song from which a trooper is constructed outside of the game, they receive points called "play points" which can be used to strengthen the Troopers in battle. Other items, called "pitch pearls", allow the Troopers' ranks to be increased. Pearls can be obtained by defeating monsters in quests and in the rehearsal room. The rehearsal room is a place where the Troopers can be trained one at a time to become stronger.
