A Sci-Fi Adventure Game of Giving Orders, Standing Back, and Waiting for Return It was supposed to be simple work — just give the orders and wait... but things didn't quite go that way. ※※※All characters, organizations, etc. appearing in this game are fictional. Any resemblance to real people or organizations is purely coincidental※※※ —————The story begins with the construction of a Galactic Federation Army satellite branch base on a rural planet at the edge of the galaxy. The protagonist arrives there fresh out of the military academy, holding the title of Acting Base Commander. You must build up this base and send starships out to resolve various crimes, conflicts, and battles, advancing the story as you solve these problems. However, the newly built base had not a single warship — not even one crew member or soldier. And so begins the lone struggle of the rookie Acting Commander————— This game is free to play, but includes advertisements. It requires periodic network access, though offline play is supported for a certain amount of time. (Ads can be removed via in-app purchase, but periodic network access is still required to obtain time.) In-app purchases of in-game items are available for sale, but the game is designed so that it can be cleared without spending money, given enough time. Game balance adjustments may occur through version updates. There is a level cap, but this cap will be raised as the story progresses. Please note that equipment strength and skills may be added or changed. ———————————————————————— This app includes a subscription-based purchase item, the "Headquarters Registered Direct Command Service."
