Battlantis (Japan, program code E)

First released in Japanese arcades in 1987 by legendary game developer Konami, Battlantis (Japan, program code E) is a cult classic fixed-screen arcade shooter that stands out from the era’s wave of sci-fi themed shooters with its unique mythological fantasy setting. This specific program code E variant is the unaltered original Japanese ROM, retaining the original difficulty balancing, enemy spawn patterns, and 8-bit chiptune soundtrack that were adjusted for later international releases of the game. Set in the sunken mythical realm of Battlantis, you take control of a sky guardian tasked with fending off waves of invading mythical creatures including harpies, centaurs, gorgons, and stone golems, all led by the tyrannical Battlantis King who aims to conquer the surface world. Unlike many fixed shooters of the time, Battlantis introduced innovative mechanics such as chargeable area attacks, temporary shield power-ups, and branching enemy movement patterns that reward strategic position

Game Guide

Mastering Battlantis (Japan, program code E) takes practice, but these tips will help you survive longer and beat the final Battlantis King boss. First, familiarize yourself with the core controls: use the left/right joystick to move your guardian ship across the bottom of the screen, tap the fire button for standard rapid shots, and hold the fire button for 2 full seconds to unleash a charged column attack that clears all enemies in a straight vertical line, including otherwise indestructible stone golem projectiles. For early waves, prioritize taking out fast-moving harpy enemies first: they fire homing fireballs that track your position, while slower centaur and goblin enemies fire slow, predictable linear projectiles that are easy to dodge. The golden shield power-up that drops after every 3 completed waves only blocks 3 incoming attacks, so avoid wasting it on minor projectiles; save it for boss fight phases where enemies fill the screen with hard-to-dodge spread fire. When you reach the Stage 5 Gorgon Queen boss, note that her only weak point is the glowing gem on her forehead, which is only exposed for 1 full second immediately after she finishes her stone gaze attack: firing before this window will cause your shots to bounce off harmlessly, wasting valuable damage time. This program code E variant has higher base difficulty than international releases, so never stay in one position for longer than 1 second: enemies will target your current position with burst fire after a short delay, so constant small movements are key to survival. Finally, collect all 3 sacred orb power ups that drop across Stages 6, 7 and 8 to unlock a 10-second full invincibility buff, which is the most efficient way to take down the final Battlantis King boss, who has 8 separate health bars. If you hit 100,000 points you will earn a free extra life, so prioritize collecting bonus coins during the Stage 7 bonus round by using rapid fire instead of slower charge shots to hit as many float
