About the 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.

What is a Steam gift and how is it different from a key?
A gift is a present our bot sends straight to your Steam account via your profile link: no code to enter, the game appears in your library once you accept the gift. A key is an activation code you enter yourself in the Steam client.
Which gift region should I choose?
The one your Steam account is registered in: Steam will not accept a gift from another region. The region is shown in your Steam account settings under "Store country". "CIS countries" means Belarus, Armenia, Georgia and other CIS countries.
How will I receive the gift?
After payment you enter a link to your Steam profile and the bot sends the gift straight to the account — you only need to accept it in Steam. It usually takes 2–5 minutes, around the clock.
What if the account already has this game?
Steam will not let you accept a gift of a game already in your library — check the library before buying. If it happens, write in the order chat: we will refund you.
