Arcen Games has announced that The Light of the Spire, the latest expansion to AI War, is now available for $10 through arcengames.com. It’ll hit digital distributors soon.

This expansion brings 180 new ships, new AI, new music, new classes and new factions, to name just a few additions. The developers have dubbed it “the game’s biggest expansion ever.”

In addition, AI War has hit version 5.0. Arcen Games remains devoted to their space strategy title with this free update. Here’s the official description of what the update brings:

“Nearly every combat ship in the game has been rebalanced in an effort to integrate all the new units added over the past year. Golems have been completely revamped and the AI have received major intelligence upgrades such as more proactive retreats, a network of core shield generators, and the new “stalking” mechanic where it lies in wait until the player is at their most vulnerable. Players should also be pleased with significant adjustments to overall difficulty and the shortening of the early part of the game — allowing you to “get to the good part” faster. Not to mention tons of performance improvements, as well as more of a general accessibility regardless of what level of player you are.”
