This one is more polish work for the new expansion, and also for the rest of the game.
– Fallen Spire has been substantially rebalanced in favor of powerful capital ships (on the human side) and powerful FS exos (on the AI side), and away from its naturally high AIP causing runaway wave sizes (due to reinforcement redirection).
– The Galaxy Map Filters have been reorganized and improved somewhat; more work needed there but it’s a start.
– And a ton of miscellaneous stuff, notes linked above for the curious.
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.
