About ‘Changeable Guardian ESTIQUE’

Faithfully ported to Steam, ‘Changeable Guardian ESTIQUE’ was created in the 21st century as a completely new title for NES ROM cartridges.

Includes both the NES version and the FC version, which have different story. 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.
