Avengers in Galactic Storm

Avengers in Galactic Storm plays similarly to other 2D versus fighting games, in which the player's character fights against his or her opponent in best two-out-of-three matches with the computer or against another player. The player has a character roster of eight playable fighters to choose from. The main unique feature of the game is the assistant character roster. Players choose both a playable character and an assistant to fight with before proceeding with the selected mode. (wikipedia.org)
