Getting Started

Welcome to Nexus Legacy — a deep space 4X strategy game where you build, research, conquer, and explore.

What is Nexus Legacy?

Nexus Legacy is a persistent browser-based space strategy game. You start with a single colony on a planet, gather resources, research technology, build fleets, and expand across a procedurally generated galaxy with thousands of star systems.

The game combines classic 4X elements — eXplore, eXpand, eXploit, eXterminate — with real-time mechanics: buildings upgrade over time, fleets travel between stars, and research unlocks new capabilities as you progress through five technological eras.

Whether you prefer peaceful economic expansion, aggressive military conquest, or cooperative alliance play, Nexus Legacy has systems to support your playstyle.

Choosing Your Commander

When you create your empire, you pick one of five commander archetypes. Each grants a different set of empire-wide passive bonuses that shape your playstyle from the start. Your pick is permanent, so choose the style you actually enjoy.

Industrialist

King of mining and production. Bonuses to raw resource output, fleet mining yield, and empire storage. Best for building heavy economies and feeding massive shipyards.

Scientist

First in technology. Faster and cheaper research, bonus energy production, and improved population growth. The tech-rush commander.

Explorer

Fortune favors the bold. More loot from expeditions, wormholes and surveys, plus faster fleets, lower fuel cost, and extra cargo. Built for the frontier.

Warlord

Victory through strength. Stronger ships, faster shield regen, cheaper fleet production, and an extra fleet slot. A pure combat commander.

Diplomat

Adaptability is survival. No fixed bonuses — instead, switches between four doctrines (industrial, research, expedition, military) over time.

Tip: Commanders give you themed bonuses, not hard restrictions — any archetype can pursue any strategy, the bonuses just make certain approaches more efficient. Your homeworld is rolled at random from the habitable types (terra, rocky, or crystalline) regardless of your pick.

Your First Colony

You begin with a single planet in the Sentinel zone — a safe zone protected by automated wardens where you can learn the game without fear of attack.

First Steps

  1. Build an Ore Mine — Ore is the foundation of everything. Get this producing first.
  2. Build a Silicate Mine — Silicates are needed for technology and advanced buildings.
  3. Build a Solar Plant — Every building consumes energy. Keep your energy balance positive.
  4. Build a Hydrogen Processor — Hydrogen fuels ships and is required for alloys.
  5. Upgrade your Research Lab — Higher lab levels unlock more advanced research.
Tip: Watch your energy balance. If energy production drops below consumption, all your resource production suffers. Build energy buildings before expanding your mines.

Early Priorities

Economy First

A strong economy funds everything else. Focus on upgrading your mines and energy buildings to level 5-8 before branching out. Build a Storage Complex once your resources start hitting the cap.

Research Path

Your Research Lab unlocks the technology tree. Early research priorities include:

See the full Research Tree for details on all five eras.

Your First Ships

Once you research Orbital Mechanics and build a Planetary Shipyard, you can construct your first ships:

Expand Carefully

Once you research Colonization Technology, you can build Colony Ships and settle new worlds. Choose your colony locations wisely:
