How to Play The 3-D Battles of WorldRunner
Quick start
Press START, then use Left and Right to line Jack up with safe ground while he runs forward. Press A early when approaching a gap; holding Up with A produces a longer jump, while Up and Down also raise or lower running speed. Hit ordinary columns to reveal items, but avoid the mushroom. A missile pickup enables B to fire, so preserve it by avoiding collisions and use it to clear enemies ahead. Watch the timer, collect clock items when available, and press SELECT only if you want to toggle the original 3-D display.
Controls
D-pad Left/Right: steer Jack. D-pad Up: speed up. D-pad Down: slow down. A: jump. Up+A: long jump. B: fire a missile when the missile power-up is active; fire during boss battles. START: start, pause, or resume play. SELECT: toggle the stereoscopic 3-D display between 3-D and 2-D.
The 3-D Battles of WorldRunner — About this game
The 3-D Battles of WorldRunner sends Jack the WorldRunner across eight planets in Solar System 517 to defeat Grax and his Serpentbeasts. Jack runs into the screen while you steer left and right, adjust his speed, and time jumps over pillars, canyons, and hostile creatures before the clock expires. Smashing certain columns reveals useful pickups such as missiles, temporary protection, extra time, bonus lives, and bonus-stage balloons, though the poisonous mushroom must be avoided. Missiles let Jack shoot during the running sections, while each world's climax turns into a direct fireball battle against a dragon-like boss. SELECT switches the red-and-blue stereoscopic presentation on or off for the game's original 3-D effect.
