Astral Battlefield

At unknown coordinates in the depths of space, there exists an AI-controlled secret base where all information about human civilization is stored. Around this base lies an area known as the "Astral Battlefield", where wars against external threats have always taken place in an abstract form.

On Earth, some humans are teleported here through "Starlight Projection" technology and form troops, while all external threats are projected as opposing forces. As a commander, your mission is to lead your troops to victory in turn-based battles on a "random" battlefield.
