From the creators of AI War: Fleet Command.

Turn-based tactical combat, with up to 5 factions competing at once.
Extremely deep simulation of an entire solar system and its billions of inhabitants. Even just watching everything unfold in Observer mode is entertaining, as nations rise and fall.
New-player-friendly ramp-up of complexity as you play, which you can disable if you're already a veteran.
Eight races each have very distinct personalities and attributes. Each one even has its own completely unique political system.
Difficulty levels split between the grand strategy and turn-based combat portions of the game, both ranging from quite casual to incredibly hardcore.
Save and reload your game with ease any time, or tough it out in ironman mode.
Composer Pablo Vega's best soundtrack to date, featuring 54 minutes of music and the vocal finale "Lay Down Your Arms."
