Justice League Heroes is an action fighting game based on the popular DC Comics series. A sinister plan, seemingly unrelated events, prove to be a threat that requires Earth's greatest superheroes: The Justice League. Genetically-engineered creatures take over a top secret facility in Finland, while military robots cause chaos in a high tech Metropolis research facility. A team of super powered criminals also seize control of a Nevada missile base.
The game features a team of DC heroes, including Superman, Batman, Wonder Woman, Green Lantern, and others, each with their unique abilities. Players can control these characters, as well as unlockable characters like Aquaman and Black Canary on the PSP version. The gameplay allows for cooperative play for two players, and the heroes' superpowers are developed through collecting experience orbs from enemies.
Players battle against DC's greatest villains, including Braniac, Killer Frost, Darkseid, and Doomsday. Boss battles are unique and challenging, with no two defeated in the same way. The game features special shield icons that can be collected to unlock characters, alternate costumes, and enhance the heroes' abilities.
The game takes players through famous locations such as Metropolis, S.T.A.R. labs, and for the first time, the Justice League's Watchtower. Superpowers can be customized using boosts, which range from enhanced damage and efficiency to luck, speed, and super power duration.
