How to Play Justice League Heroes: The Flash
Quick start
Choose one of the three save slots and begin Story. In the opening stages, line the Flash up with enemies before attacking, clear each wave and follow the route to the next area; the campaign spans 12 stages and boss fights including Gorilla Grodd, Killer Frost, Zoom, Circe and Brainiac. Build energy with basic punch combos, use the auto-target dash to close distance, and save Flash Speed for groups or a dangerous boss pattern because it drains energy rapidly. Justice League assists are limited and used in a fixed order, so keep them for crowded screens rather than single enemies.
Controls
D-pad: move left/right and into/out of the foreground; navigate menus. B: punch, with repeated taps forming a combo. A: auto-target dash to a nearby enemy, consuming energy. A+B: jumping kick. R: Flash Speed, slowing enemies while draining energy. L: summon the next available Justice League assist for a screen attack. Later moves: hold B and rotate the D-pad 360 degrees for the run-around/tornado attack; hold B and quickly press Up then Down for ground pound. START: pause. Three save slots preserve campaign progress.
