Avengers in Galactic Storm is a fighting arcade game developed and published by Data East. It features a single or two-player story mode or multiplayer head-to-head mode, and was the first modern fighting game to feature assistant characters commonly referred to by gamers either as "helpers" or "strikers". The game is based on characters in the Marvel universe, primarily The Avengers but also the Kree. The game's plot and roster of playable characters is based on the Operation: Galactic Storm story arc. The player has a character roster of eight playable fighters to choose from, each with their moves and fighting styles from the comics.
