AI War 2: The Spire Rises Rises

AI War 2: The Spire Rises is now available on Steam for AI War 2, the sci-fi strategy sequel for Windows, macOS, and Linux. Here's a trailer with a look at the expansion, and here's word on what it includes:
In addition to some new capturables, turrets, and other ships that are available in any game once this expansion is installed, there are two major new factions. The Scourge is your greatest foe, the smartest and most dangerous sub-group of the AI. The Fallen Spire is your greatest ally, providing you with unprecedented firepower.

You can use both factions, either, or neither in your campaigns as you wish. Thanks to lobby customization options, you can even force the Scourge to be your ally against other foes, if you prefer.
