Idinaloq

About

Extraterrestrial mechanized marauders have arrived in near-future Earth orbit, launching an attack on the planet which must be repelled. Four pilots are qualified to pilot Idinaloq, humanity's ultimate spacefaring weapon. Sayuri, EIRIA, Irene, and Formera...these capable yet troubled women, together with their operator Tomomi, are the last defense against annihilation.

Idinaloq is a short, historically acclaimed Windows arcade shoot-em-up, with a mix of classic '90s design and forward-looking mechanics. The game debuted at both Comiket events in 1999, sold there before becoming online freeware.
