This one is a relatively small release, for us, but the impact on the endgame should be... interesting. It's the last of the non-champion-related new content for Ancient Shadows and adds 3 new Core Guard Posts that the AI can use its "brutal" picks on when populating an AI homeworld's defenses during mapgen. They're all beatable, but they'll take a chunk out of your fleet(s) first. Balance feedback is welcome, as always.
This is a standard update that you can download through the in-game updater itself, if you already have 4.000 or later. When you launch the game, you'll see the notice of the update having been found if you're connected to the Internet at the time. If you don't have 4.000 or later, you can download that here.
