About Heroes of Science and Fiction - Xenauri faction

Heroes of Science and Fiction - Xenauri faction - about the game

Heroes of Science and Fiction is a turn-based strategy game with RPG elements set in a sci-fi universe. Players lead commanders and armies from distinct factions across planetary maps in the isolated Siren System, gathering resources, upgrading bases, and engaging in tactical battles. The title draws from classic hero-led strategy formulas while introducing sci-fi mechanics such as unique faction abilities and commander progression systems.

Gameplay

Core gameplay revolves around exploration of map-based planets where commanders move armies to secure resource nodes, recruit units, and expand bases. Each turn allows movement, construction, and preparation for conflicts that resolve on a hexagonal combat grid. Units advance and attack in sequence, with positioning and abilities determining outcomes. Heroes gain experience through battles and exploration, unlocking skills from a pool of 24 options along with equipment, artifacts, and consumables that modify stats or provide battlefield effects. Commanders also access 54 active abilities tailored to their role.

The Xenauri faction emphasizes close-quarters dominance. These warriors excel with blades and rely on the speed of lizard mounts for mobility despite heavy armor. Some members develop into altari psychers who channel unseen energies to support combat. Their nomadic lifestyle carries over to the Siren System, where bases feature temporary shelters from landing craft, halls adorned with giant lizard skulls, and crystals transported from their homeworld of crystal shards and diamond mountains. A young Xenauri commander leads forces through the invasion's aftermath under the guidance of the Pathfinder prophet.

Game Modes

Single-player campaigns deliver narrative-driven experiences across multiple levels per faction, focusing on story progression and faction-specific challenges. Skirmish maps support standalone matches with customizable setups on over 20 environments. Multiplayer options include online PvP for competitive matches and co-op sessions where players share objectives or split-screen play. Additional features such as a map editor and random map generator expand replayability for custom scenarios.

Each of the five factions offers seven upgradeable unit types, a signature skill, and multiple commanders with distinct progression paths. Resource management covers materials like biomass and polymers to fuel base development and army recruitment.

Faction Dynamics and Strategy

Factions differentiate through unit compositions and playstyles. The Xenauri prioritize melee aggression balanced by mount speed and occasional psionic support. Other groups bring contrasting approaches, such as numerical superiority or technological edges, creating varied strategic matchups. Players adapt tactics based on terrain, enemy composition, and resource availability during both campaign missions and skirmishes.

Is It Worth Playing?

The game suits fans of turn-based strategy who enjoy hero progression, base management, and tactical combat in a sci-fi setting. Full release includes all five factions, multiple campaigns with four levels each, extensive skirmish content, and multiplayer support. Positive player feedback highlights the depth of commander customization and faction variety. Those seeking a modern take on established strategy mechanics with narrative campaigns and competitive options will find substantial content here. Availability on PC platforms makes it accessible for both solo campaigns and group play.
