About Heroes of Science and Fiction
Heroes of Science and Fiction (formerly Silence of the Siren) is a turn-based strategy game where you command one of several space-faring civilizations vying for control of a distant star system. Explore planets, secure resources, build cities, and raise armies to defeat your opponents. The full game includes 5 playable factions, 4 campaigns with 4 levels each, and 30 skirmish maps set in colorful environments.
Each faction brings its own unique base, 7 upgradeable unit types, a special skill, and a set of commanders to choose from. With 24 skills, 54 active commander abilities, and various equipment, consumables, and artifacts, you can customize your strategy. The Siren star system, once a galactic alliance, is now isolated and fractured, with ruins of a lost Primals civilization scattered across its planets.
As you venture deeper into uncharted regions, you'll uncover an ominous presence—an entity or echo from below. Build and upgrade your bases with advanced technology, hire massive armies, and recruit skilled commanders. Overcome obstacles to gather powerful equipment and ancient artifacts that give you an edge in battle.
Engage in turn-based combat where tactical thinking is key. Learn unique unit moves, deploy commander abilities, and outsmart stronger opponents. The game combines old-school strategy with modern controls and an intuitive UI, offering a rich sci-fi experience for fans of the genre.
