Tales of Symphonia: Dawn of the New World takes place two years after the events in Tales of Symphonia. You play as Emil and Marta and many other characters who each have special abilities. In Tales of Symphonia II, you will be able to play in multiplayer co-op with up to four players during battle.
The new exciting thing about this game is the ability to recruit over 200 different monsters and put them in your party to fight alongside you. To capture these monsters there will be an "elemental alignment system" where you must match with your attacks.
Tales of Symphonia: Dawn of the New World will be released on November 11th, exclusively for the Nintendo Wii.
