Get ready to protect the entire solar system from an unprecedented threat - the D'Ahari, a race of insect-like aliens. Control an entire fleet of spaceships, trade with other races of an Alliance, and develop your own space station.
The enemy is advancing and terrorizing civilians of the Alliance. You will have to protect miners, builders, traders and even experienced fighters. Tactics and strategy are above all else. One wrong move and you will lose your fleet. Remember, every ship here is worth a lot.
The station you were given requires servicing. Plan which modules to install and which to remove. Produce resources for sale or use them to charge abilities.
Move between planets, trade, hire pilots. The entire solar system is at your fingertips.
Three classes of ships and dozens of models. Each ship is unique. Many of them needs to be unlocked.
