Evaluation

Heroes of Science and Fiction launched into full 1.0 release on March 17, 2026, after roughly 18 months in Early Access (September 2024 to March 2026). At launch, the developer confirmed more content was coming, and they have delivered consistently since then. The first paid DLC — the Typhon Map Pack — shipped on June 22, 2026, alongside a substantial free "Underground" update (Update #8) that added new units, an underground map layer, and the Hero Action Planner. The developer closed that announcement by stating they are "off to continue working on the mysterious new faction DLC," making clear that a new faction is in active development as a future paid DLC. The July 16, 2026 Update #9 post reinforces this, stating that "the next post will hopefully bring some news about upcoming DLC." A hotfix followed on July 20, 2026, showing the team remains actively engaged. All of this follows a pattern of regular updates since 1.0 launch, including feature patches roughly every 2–4 weeks. There is also a roadmap published on April 14, 2026 that outlined two teased DLCs — one of which has now shipped (Typhon Map Pack), with the second (the new faction DLC) still in development based on the developer's own post-release statements.

About this game

Heroes of Science and Fiction (formerly known as Silence of the Siren) is a turn-based strategy game where several different space-faring civilizations fight over control of a distant star system. Explore what’s left on the planets and secure resources to build mighty cities. Raise powerful armies and defeat your opponents on the battlefield!

Content in the full game

Heroes of Science and Fiction contains 5 playable factions, four campaigns with 4 levels each and 30+ skirmish maps set in colorful environments.

Each faction brings its own base, 7 upgradeable unit types, a special skill and a set of commanders to choose from. There are 24 skills, 54 active commander abilities and various pieces of equipment, consumables and artifacts.

The Siren star system, birthplace of a galactic alliance, and the homeworld of a lost Primals civilization, has been cut from the rest of the galaxy. As a result, the carefully built alliance split into bickering factions and secluded colonies. These days, hardly anyone pays attention to the ruins scattered all over the few habitable planets of a freshly isolated system. The deeper you venture into the uncharted regions, the stronger the feeling of endangerment grows. There is something else. An entity, a shade, an echo of whispers from below.

Explore what's left on the planets and secure important resources. Use them to upgrade your bases with advanced technology and to hire massive armies. Play as several different factions, recruit skilled commanders, teach them new skills and lead them into battle. Overcome obstacles on the map to gather powerful equipment and ancient artifacts.

Encounter a wide range of enemies in turn-based combat, use your tactical thinking to gain advantage on the battlefield. Learn the unique moves of your units, deploy your commander's special abilities and outsmart even much stronger opponents.

  • Explore a rich sci-fi world and discover secrets of a lost civilization

  • Collect powerful artifacts, secure important resources, upgrade your bases and hire the strongest units

  • Level-up your commanders and crush your opponents in exciting turn-based battles

  • Take control over several different species and factions
