Dominus Galaxia

Dominus Galaxia is a 4X space strategy game built around strategic decisions, with systems intended to reduce non-strategic busywork. You expand across space, manage colonies and fleets, research technology, design ships, and deal with other powers through diplomacy, intelligence and combat.

Manage your empire

Colony management and fleet movement use sliders, with no build queues to micromanage. You can choose how expansion works: build colony ships, build starports or send colonists directly. Other customizable options include research modes and whether starlanes are present, changing how a game plays.

The infinite, semi-random technology tree is divided into six fields, which you can research concurrently. You can also design ships in depth, with an optional crafting component described as Diablo-esque. Diplomacy includes tech trading designed to be less exploitable, and a relationship system: high relationships help maximize trade revenue, while low relationships make spying more difficult. Exploration and spying help you assess opponents’ power across various categories.

Fight across the stars

Combat is turn-based and takes place on a hex grid. Terrain types and powerful special devices shape battles, which can involve more than two sides. Strategic terrain includes impassable, slow and sensor-blocking nebulae, as well as optional starlanes and transient wormholes.

Planetary bombardment and invasion are also available. You can auto-resolve battles at any time, or begin one manually and instantly resolve the remainder after a number of turns. Battles that happen in the background use the same logic as battles involving the player.

Game modes

Hotseat multiplayer lets players take turns on the same setup. Deathmatch and Team Deathmatch offer modes focused on warfare rather than diplomacy.

You can choose between static and adaptive AI. AI production bonuses can be set independently of skill level, so you can face smart opponents with less production, less capable ones with more, or settings in between.

Modding

Text files can be used to adjust many game mechanics, and the game includes modding capabilities.
