All be it a bit short, there is plenty of replay ability here in the form of multiplayer action and arcade fun after the story has ended.
Throughout the story you play as each superhero and follow their story for three or four "stages". Each level has its own small story but all in a round about way, come back to the main plot. I would not change a single thing about this game. It was for me, absolutely perfect.
The graphics were amazing, sound effects are spot on and controls were easy to grasp, yet not so simple that you resorted to button bashing. I would recommend you play this with a controller however, can't imagine it being a breeze to play on keyboard.
