You are a gunner bolted to a cross of rails while waves of drones swarm in from the edges of the screen. Some drones chew through the rail and red ones drop cargo that turns into mines at the central hub, so every shot is a choice between protecting the track and protecting yourself. Power-up parcels give you double score, double damage, repairs, extra lives and a screen-clearing bomb that you must time well. Clear each wave's kill quota to earn a rank and face a tougher wave.

Objective • Shoot the drones before they destroy the rail or stack up mines at the hub. • Meet the kill quota to finish each wave; four mines plus a centre pass, or a collapsed rail, ends the game. Controls • Joystick (port 2): move along the rail you are on. • Push the joystick across the rail to turn your gun barrel, or switch rails at the crossing. • Fire: shoot (hold for continuous fire); also starts the game. • Keyboard alternative: W/A/S/D to move, Space to fire. • S on the title screen shows the story, I shows the instructions. Tips • Pick up parcels as they arrive: points, 2x score, 2x damage, repair, extra life and clear. • A clear arms on pickup and wipes mines and cargo on your next pass through the centre, so grab it when cargo is piling up. • Red drones carry the cargo that becomes mines; shoot them first. Modes • 1 player, endless waves with a high-score table (up/down to pick letters, fire to confirm).
