Season's greetings everyone!

In the spirit of Christmas, we want to share our thanks for your glorious support by releasing one massive update to close off the year. It is truly giant, featuring the long-awaited Unit Split, completely differentiating the two human factions, Centauri and Sol. This adds a total of 21 new units and 13 new structures, fully nailing down the distinction between the two.

Performance is also greatly improved thanks to a plethora of optimizations leading to much smoother gameplay, even on older systems.

But that is not all, and so to keep things simple and intuitive, here is a rough rundown of what to expect in the update:

  • 21 new units, 13 new structures, completely differentiating the two human factions.

  • 2 new maps to play on (Crystal Chasm and Whispering Plains).

  • FPS Commanding (using the F key), which allows you to group up with fellow units in the battlefield when playing as boots on the ground infantry and aliens.

  • Massive improvements to Sandbox, laying the foundations for custom mission creation soon.

  • Vast performance optimizations, boosting the experience overall.

  • Numerous configurable options for Strategy, from starting distances to tech tier limits.

  • Overhauled main menu to better distinguish the various forms of play.

  • Revamped vote screen and role selection UI.

  • Deep structure foundations allowing significantly improved structure placement.

  • Unlinked structure decay, where structures degrade/die when not connected to a HQ or Nest.

  • Balanced structure health, making back and forth exchanges more common and enjoyable.

  • Tech tier system now based around the team rather than structure, dropping to 0 if the Research Facility is destroyed but returning to previous level when rebuilt.

  • Harvester improvements to prevent them getting stuck on Refineries.

With this update live, we now deep-dive entirely into AI and the Campaign, laser-focused on delivering a polished experience for 1.0, which we expect to release sometime next year.

So on that note, enjoy the update — and once more, a giant thank you for supporting us and believing in us. We truly are eternally grateful.

Kind and sincere regards from the dev team!

"The palms gently rustled in the morning wind as the heat of Baltarus ramped up, the majestic flags of Sol, our home, swaying in the breeze. The warm silence left a certain sense of unease. Not a moment passed before we received the distress call. The Centauri had launched a massive assault. It was our saving grace that a Dropship arrived just before the enemy reached us, taking us to safety. We lost many good men in that defence, their sacrifice will not be in vain.
