Caverns of Mars

The object of Conquest of Mars is to guide your ship through the Martian caverns and reach the base. Once there, you must activate the Destructo-Bomb
and escape before the timer expires and the cavern explodes!

Use the joystick to navigate your ship through the different stages to avoid colliding with the cavern walls. You can move your ship left and right to maneuver through the winding
caverns. You can also move your ship up and down to attack or retreat from enemy targets.

Press the fire button to launch your dual missiles to destroy the enemy installations, including generators, cannons and fuel pods. When you fire missiles, you cannot fire again
until both missiles have either destroyed an enemy target, collided with the cavern walls, or have exited the bottom of the screen so plan your shots wisely!
