Satazius creator Astro Port, the side-scroller is described as an homage to mech shooters of the 16-bit era, such as Cybernator and Mech Warrior.
Gigantic Army has players taking control of a manned combat robot known as "GMR-34 SALADIN," customizing a set of explosive, projectile and plasma weapons across six stages. The game includes four difficulty modes and 12 "mid and end level" bosses. The developer is working to bring the game to Linux, and is currently vying for a spot on Steam via Greenlight.
The game is published by Nyu Media, which announced its localization plans for Gigantic Army in addition to other Japanese indie games like the crowdfunded Yatagarasu: Attack on Cataclysm in October 2013.
