Cosmic Supremacy

Cosmic Supremacy is a FREE tick/turn-based massively multiplayer space strategy game with a 3D 'Galaxy View' interface. You share a galaxy with hundreds of players each with their own alien civilization. Some of them might turn out to be your enemies, others could be your allies. You need to explore the galaxy around you, discover new solar systems, colonise new planets, and expand your empire. You can design every ship in your fleet, and research new advanced technologies so that you can build faster and stronger ships that will give you the edge in epic battles.
 
Cosmic Supremacy is FREE TO PLAY!
 
As a game in the 4X genre (eXplore, eXpand, eXploit, eXterminate), Cosmic Supremacy draws inspiration from the hundreds of browser-based games out there, but we did not want to add yet another one - instead we took the basic idea to the next level; the Fifth X: eXperience. Cosmic Supremacy is played with a very slim downloadable client allowing features that are not found in any other game. We left the shortcomings of existing games behind and designed Cosmic Supremacy from the ground up to be the best game in its class.

If you are into online space strategy games, then Cosmic Supremacy might be just what you have been looking for!
