How to Play Baltron
Quick start
Use the D-pad to move in 8 directions, and press A repeatedly to shoot in the air and on the ground. Before you get too close to the edge of the screen, read the flow of enemy bullets and use B + left/right to switch direction and create a retreat. In times of danger, use smart bombs on B+, and use warp on B+ when moving quickly, but always be careful of your remaining energy.
Controls
D-pad: Move in 8 directions. A button: Fires air and ground bullets. B+Left/Right: Reverse scroll direction. B+Top: Smart Bomb. B+Down: Warp. START: Pause.
Baltron — About this game
"Valtron" is a side-scrolling shooting game for the Famicom in which the player pilots the fighter plane Dystorius and takes on the Baltron army. The scrolling speed changes depending on the left and right position of your aircraft, and you can use the combination of the B button and direction keys to reverse the direction of travel, use smart bombs to wipe out enemies, and warp to move forward. Energy continues to decrease during flight, so it is important not only to avoid enemies and terrain, but also to make decisions about replenishment. Break through long lines by firing regular shots that fire both air and ground bullets at the same time.
