What is stellaris alien machine?

Stellaris is a science-fiction strategy game, where players can encounter a variety of alien species. One such alien species is the "Machine Empire," a race of sentient machines that have supplanted their organic creators. These machines possess advanced technology and can rapidly expand their borders, making them a formidable force in the galaxy. They have a unique playstyle, in that they don't require food or consumer goods, but instead run on energy, minerals, and alloys. Additionally, they have a reduced capacity for diplomacy with organic species, as they tend to view non-machines as inferior and expendable. Players can choose to play as the Machine Empire or encounter them as an opponent in their campaign to dominate the galaxy.
