Overview

About this game

Feel your pulse quicken while piloting your 150,000t warship between asteroids in the vacuum of space in real time. All with fully simulated physics.

Balance material requirements with power, tonnage, and size while building your fleet to maximum efficiency, piece by piece, module by module. Will you create a large number of smaller, more nimble vessels or double down on a massive station packed with firepower?

Harvest and process valuable materials from asteroids for your profit margins, or use the bountiful resources for the maintenance and expansion of your own mercenary fleet while doing missions for the highest bidders in the sector.

Research for new modules and tools to keep expanding your fleet of ships and mining stations. Build link gates to gain access to new riches in new sectors of space.

The more you mine, the more you build and the greedier you get, the higher your heat signature becomes. Once it reaches critical levels, the aliens will detect you. Defend your fleet at all costs using defense systems and ships of your design.
