In a high-tech Metropolis research facility, military robots wreak havoc. Genetically engineered creatures take over the top-secret Deep Space Communications Array in Finland. A group of superpowered criminals who have never worked together before seize a missile base in Nevada. And dozens of alien warriors are freed from their long imprisonment deep beneath the surface of Mars… These seemingly unrelated events reveal themselves as components of a sinister plan, and it will take Earth’s most excellent superhero team to stop it: The Justice League! Justice League Heroes is a two-player cooperative action game based on the popular D.C. Comics series. Superman, Batman, Wonder Woman, Green Lantern, Martian Manhunter, The Flash, Zatanna, and a slew of unlockable characters like Aquaman, Green Arrow, Hawkgirl, Huntress, Hal Jordan, and Kyle Rayner are all under your command.
Furthermore, the PSP version includes two exclusive, unlockable heroes: Supergirl and Black Canary. Players must fight through iconic locations such as Metropolis, S.T.A.R. labs, and, for the first time, the Justice League’s Watchtower. Many of D.C.’s greatest villains, including Brainiac, Killer Frost, Darkseid, and Doomsday, face off against our heroes. Boss battles are ferocious and one-of-a-kind, with no two defeated in the same way.
