Unigame

A game by @demonarokden on Spawn.

Genre: Strategy, Sandbox, MMO

Grow a colony on a rust planet, build a fleet and raid your way to the pirate Warlord's citadel.

From the maker

I missed the golden era of classic text-based space strategy. I wanted to create a fair, deep, and highly competitive universe where your tactical decisions and alliances matter more than flashy graphics.

A persistent sci-fi strategy game where you build an empire from scratch. You will manage resources, research technologies, and build a massive fleet to defend your colonies or conquer your rivals in real-time.

My inspiration were the games ogame and space invasion.

Looking forward to your feedback to build the future of the game together!
