Welcome to Rezium

Build - Mine - Conquer

Rezium is a space strategy game where players build bases, mine resources, and conquer new planets across the galaxy.

Set in the year 2385, the game revolves around Rezium, an extraordinary mineral with the molecular power to terraform barren worlds, making it humanity's most prized resource and a pivotal driving force for overall narrative of the game and storyline.

The game combines 4X and RTS elements, starting with single player in the demo and moving into persistent multiplayer functionality in the first full version of the game.

Game Overview

In Rezium, players will:

• Establish and expand a base on Mars, optimizing energy distribution, worker allocation, local mining operations and spacecraft manufacturing.​

• Explore asteroids, planets and moons to mine valuable minerals and resources that can be traded for currency and game items such as spacecraft, mining equipment and ExoGate access into further star systems.

• Conquer new frontiers by establishing bases and engaging in strategic battles against rival factions to control key territories, trade routes and resource rich planets.

The first playable vertical slice version of the game was completed in November 2025, and is currently available on Steam via a Key request through Discord. In 2026, the team is building a Demo to work on main systems, and further gather community feedback to help validate the game design and guide further development.

Rezium Demo is targeted for public release on Steam in October 2026. Version 1 is targeted for release on PC via Steam in Q4 2027. ​
