The Teen Titans receive a video game in the mail, one that is starring them. When Cyborg and Beast Boy try to play it, they all get placed inside of the video game's world. They go through various levels as they try to figure out how to return home, fighting against several enemies and villains they have faced off against before. After the Titans defeat most of the villains, Slade appears before them, making Robin suspect that he was behind everything, but Slade, too, is part of the program. The Master of Games then reveals himself as the mastermind, but after the Titans capture him, they find that he is not the true culprit. Breaking the fourth wall, the Titans reveal that the player is behind everything.
Main characters
Robin - The most agile titan. His melee attacks consist of punches, kicks, and using his bo to strike opponents and objects. His ranged attack is the "Birdarang". He has a double jump.
Raven - The all-around titan. Her melee attacks consist of close-range blows and strikes. Her ranged attacks are based on telekinesis. Her titanic attack can cover a whole room. Her "Shadow of Azarath" attack is a combo, and is also part of her titanic attack and her 'O' charge.
Cyborg - The close-range titan. His melee attacks consist of punches and his ranged attack is the "Sonic Cannon". His super attack makes him move fast while barging through enemies as he goes along.
Starfire - The long-range titan. Her melee attacks are punches and her ranged attack consists of "Starbolts". The Starbolts deal a lot of damage. She can also shoot them quickly, making them effective when dealing with targets at a distance while keeping on the offensive.
Beast Boy - The unique titan. His melee attacks consist of simple punches while his ranged attacks are based on different transformations.
