About this game
The ultimate, brand-new 8-bit shoot 'em up created in the 21st century, "Changeable Guardian ESTIQUE," has arrived on Steam!
About ‘Changeable Guardian ESTIQUE’
"Changeable Guardian ESTIQUE"—meticulously crafted to capture a truly nostalgic 8-bit feel—has been faithfully ported to Steam.
It features both the Japanese and North American versions, each offering a distinct storyline. Enjoy printed materials and various visuals in Gallery Mode.
Simple Yet Deep Game System
This side-scrolling shooter features six stages themed after cities around the world.
The super-variable robot “Estique” can transform at any time between the “Fighter Form,” which has a small vertical hitbox, and the “Robot Form,” which nullifies terrain damage and excels at recovery. Mastering the strategic switching between these two forms and two types of equipment is key to clearing the game. Furthermore, the scoring system utilizing the “Super Weapon” special attack—activated by rapid-firing the shot button—adds depth to the gameplay.
With a life system that regenerates over time and the removal of power-ups, the game design prioritizes accessibility. A strategic shooting experience awaits you, enjoyable for everyone from beginners to advanced players.
Story

Friendly planet, Petelgeuse, decided to save the Earth from space pirates and send reinforcement. Ace pirots, Mary and Kanon, ride on ESTIQUE and now launching to the Earth. Mary, you must be the messiah of the Earth. A tomorrow winner is you!
