A team of genetically engineered creatures takes over a top secret communications array in Finland, while military robots wreak havoc in a Metropolis research facility. Meanwhile, super powered criminals seize control of a Nevada missile base and dozens of alien warriors are released on Mars. These seemingly unrelated events are part of a sinister plan that will require Earth's greatest superheroes to stop it: The Justice League.
Justice League Heroes is an action game based on the DC Comics series, where players control iconic heroes like Superman, Batman, and Wonder Woman, as well as unlockable characters such as Aquaman and Green Arrow. For the PSP version, exclusive unlockable heroes include Supergirl and Black Canary.
Players battle through famous locations, including Metropolis, S.T.A.R. labs, and for the first time, the Justice League's Watchtower. The game features a variety of DC's greatest villains, including Braniac, Killer Frost, Darkseid, and Doomsday, with boss battles that are unique and require different strategies to defeat.
Superpowers can be developed through experience orbs collected from enemies, which can also be combined to create more powerful boosts. These boosts can enhance damage, efficiency, attack range, luck, speed, or superpower duration. Players can allocate their orbs and boosts to customize their heroes to suit their playing style.
Special shield icons can be collected and spent to unlock characters and alternate costumes, which affect the heroes' abilities and appearances. With this customization option, players can tailor their experience to their preferred playstyle.
