Justice League - Injustice for All (USA)

Released in 2002 by publisher Midway for the Game Boy Advance, Justice League: Injustice for All (USA) is an action-adventure beat 'em up adapted from the popular DC animated Justice League series of the same era. Developed by Saffire, the game lets players step into the roles of seven core Justice League members: Superman, Batman, Wonder Woman, the Flash, Green Lantern, Martian Manhunter, and Hawkgirl, each with unique signature abilities that change how you approach combat and environmental puzzles. The story follows the League as they respond to a coordinated attack by DC’s most dangerous villains, led by Lex Luthor and the Joker, who have formed the "Injustice Gang" to hijack global communications and eliminate the League once and for all. Spanning 12 distinct levels that take you from crime-ridden Gotham City streets to an undersea base and an orbiting space station, the game was built specifically for GBA hardware, delivering smooth side-scrolling action and colorful sprite art t

Game Guide

Mastering Justice League: Injustice for All on GBA starts with leaning into the game’s core mechanic: on-the-fly character swapping. Use the GBA’s L and R shoulder buttons to swap between your unlocked heroes at any time, and always match your hero to the challenge at hand. For heavy combat and wide platforming gaps, bring in Superman: his super strength takes out most common enemies in two hits, and his high jump clears gaps that slower, shorter heroes cannot. For puzzle sections with locked terminals, traps, or far-off targets, swap to Batman, whose batarangs and grappling hook can solve puzzles no other hero can. When navigating moving platform sections or fighting flying enemies, use Green Lantern’s ability to spawn temporary solid platforms to make these sections far easier than struggling through with a melee-focused hero. For boss fights, always learn attack patterns first: most bosses like the Joker or Lex Luthor have clear visual tells before their heavy-damage attacks, so swap to a long-range hero to avoid unnecessary hits. Remember that every hero has their own separate health bar, so swap out low-health heroes immediately and let them heal when you pick up health drops from defeated enemies. Don’t ignore the hidden League emblems scattered across every level: collecting all emblems in a stage unlocks bonus concept art and a harder difficulty mode for repeat play. Save your full super meter for boss fights instead of wasting it on regular enemy groups, as a full super attack can take out nearly half of a final boss’s health in one hit. If you get stuck on precision platforming, use the Flash’s high speed to make quick, accurate jumps that other heroes can’t pull off.
