How to Play Radical Rex
Quick start
Guide Rex through prehistoric stages, defeat enemies with fire breath, tail attacks, roars, and jumps, and collect health before the boss. Build speed for long gaps, use the skateboard sections to preserve momentum, and search vertical routes for bonus items. Avoid landing directly beside enemies after a blind jump.
Controls
D-pad: move, crouch, climb, and aim. A: fire breath or roar according to power. B: jump. C: tail attack or secondary action. Start pauses. Hold a direction to build speed, steer in the air, and use the skateboard’s momentum rather than braking before ramps.
