Steam's AI War: Fleet Command Page now offers AI War: Light of the Spire, the new expansion for AI War: Fleet Command. Here's word on what this offers: "Light of the Spire also brings 180 new ships, including the powerful 'Spirecraft' vessel class which stands as the second largest unit class in the game. New music from composer Pablo Vega, new AI types, map types, bonus ship classes, minor factions and quite a bit more packs the expansion to the brim. Prepare for a new war!" To celebrate, Steam is offering the base game for 50% off as well as a 10% discount on the new expansion. There's also a new automatic update that brings the game to version 5.0. Here's word on the patch: "With this update, 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." Finally, Steam also offers an updated AI War: Fleet Command demo, and Arcen Games has PC and Mac playable demos for the game and the new add-on.
