About this game
You are Vanguard Unit 4, the last hope of a dying universe. Your mission: build a Phase Gate in an uncharted continuum to evacuate the fleeing remnants of your civilization before reality itself collapses.
But this new dimension is not empty. It is defended by crystalline lifeforms that see you as an invader. They will stop at nothing to destroy your creation.
The clock is ticking. With every passing moment, your home universe decays. The fleet is counting on you. Will you hold the line and open the path to salvation?
Eventide Matter features:
Mine 6 unique materials and craft them into advanced components.
Research dozens of permanent upgrades in a sprawling tech tree.
Unlock and enhance around 10 module types, including lasers, thrusters, tractor beams, drones, and shields.
Assemble the complex portal piece by piece, through multiple intricate layers.
Survive relentless enemies that pursue you and seek to destroy your progress.
