Terra Invicta is a global 4X strategy in which the main task is to provide an effective counter to the alien invasion. The alien fleet has concentrated on the edge of the Galaxy, and is gradually conquering new regions, approaching Earth. But humanity does not have unity in the matter of confronting the threat, and the major world factions begin an ideological feud in which everyone wants to solve the problem in their own way. Taking the side of one of them, the player will be seduced by force or cunning to implement his own plan, not shunning any means, because the existence of civilization is at stake.
