The Zenith Remnant is AI War’s first expansion, and focuses both on adding capturable units and a new minor faction called the Zenith to the game. Arcen maintains an exhaustive list of features, but highlight features are as follows:
* Golems, which have many similar properties to Supreme Commander’s “Experimentals”.
* Several new base ship types, further expanding on the available choices for the player as well as making the AI a more devious opponent.
* New AI types that took advantage of many of the capturables introduced, as well as some that use Zenith ships.
* Over 40 minutes of new music tracks composed by Arcen Games’ composer, Pablo Vega.
* A new class of “Experimental” ships that offer abilities one would not ordinarily find in AI war ships.
