How to Play Robocco Wars
Quick start
Press START on the title. On the first ground, walk left and right, and try jumping with a short press of A and a long press to get a feel for landing on the platform. If you hold down B, you can fire continuously, so you can pick up recovery items and reinforcement items while shooting enemies in your direction. Once in the air, use the cross keys to move up, down, left, and right, and use B's forward attacks and A's downward bombs. A on the underwater surface turns into an upward missile. Prepare your physical strength and weapons in preparation for the boss, and don't force yourself to retrieve items when it's dangerous.
Controls
Cross key: Move left and right on the ground, move up, down, left and right in the air and underwater. A: Jump on the ground (adjust height by pressing length), bomb downwards in the air, missile upwards in the water. B: Normal attack forward, press and hold to fire continuously. START: Start, Pause/Resume. SELECT: Not used. On the continue screen, select YES with the four-way controller and confirm with A.
Robocco Wars — About this game
In "Robokko Wars", the small robot R-10 aims for the CUBE CASTLE where the demon king BLACK BLITZ is located. On the ground, you use jumping and shooting to cross scaffolding, in the air you fight as an airplane, and in the water you fight as a submarine, so the way you play changes depending on where you go. The role of the A button also changes from jumping on the ground to bombing in the air and upward missiles in the water, so it's important to use it properly for forward attacks. There are items you can get by defeating enemies that strengthen your weapons and restore your physical strength, so increasing your heart limit will help you prepare for the difficult points ahead. A strong enemy awaits at the end of each stage, and cute scenery and tough battles intertwine throughout all 10 stages. In the sky and sea, be careful not only of the enemies in front of you, but also of attacks and obstacles coming from above and below.
