About Heroes of Science and Fiction
Heroes of Science and Fiction is a turn‑based strategy title where multiple space‑faring civilizations vie for dominance in the isolated Siren star system. Players explore planetary ruins, gather resources, and upgrade bases before fielding armies on tactical battle maps.
The full release offers five playable factions, each with a unique base, seven upgradeable unit types, a special skill, and a roster of commanders. Four campaigns (four levels each) and over thirty skirmish maps provide single‑player and multiplayer challenges across colorful sci‑fi environments.
01 / THE GUIDE
Factions and Commander Setup
Each of the five factions supplies its own base layout, a set of seven unit types that can be upgraded, and a distinct special skill. Commanders are chosen from a faction‑specific pool, and they bring 54 active abilities that can be employed during combat.
The game also includes 24 separate skills that commanders can learn, allowing players to customize tactical options before battles begin. This structure creates varied strategic approaches depending on the chosen civilization.
- Compare the special skill of each faction to find a playstyle that matches your preferred tactics.
- Experiment with different commanders early to discover which active abilities complement your unit upgrades.

Campaign and Skirmish Modes
The game features four narrative campaigns, each composed of four levels, delivering a structured single‑player experience. In addition, more than thirty skirmish maps are available for quick, stand‑alone battles.
Both campaign and skirmish play take place on varied, colorful environments, with skirmish maps letting players test strategies against AI opponents or human rivals in different settings.
- Start with campaign levels to learn unit interactions before tackling skirmish maps.
- Use skirmish maps to practice specific commander abilities without narrative constraints.

Resource Management and Base Upgrades
Exploration of planetary surfaces yields resources that are essential for upgrading bases with advanced technology. Upgraded bases, in turn, enable the recruitment of more powerful armies and the acquisition of equipment.
Securing these resources also opens the chance to collect artifacts, which add further depth to the upgrade system and can influence later battles.
- Prioritize resource‑rich locations early to accelerate base development.
- Balance artifact collection with unit recruitment to avoid over‑committing to one path.

Multiplayer Options
Heroes of Science and Fiction supports a range of multiplayer configurations, including online PvP, LAN PvP, and shared/split‑screen play for both competitive and cooperative modes. Players can join friends locally or over the internet to test their strategies.
Co‑op modes allow teams to combine forces, while PvP pits factions directly against each other, drawing on the game's units and commanders.
- Try split‑screen co‑op to coordinate commander abilities in real time.
- Use LAN PvP for low‑latency matches when playing with nearby friends.
