New beta build! https://wiki.arcengames.com/index.php?title=AI_War_2:Multiplayer_Alpha_And_Beta#Beta_2.727_Tech_Refunds_And_Balance_Tuning You need to use the current_beta branch on Steam or GOG to play this one. If you have trouble with it, there is a most_recent_stable_beta, now, too. Feels like this one took forever, and it's absolutely huge. The headline feature #1 is that now you can spend 2 hacking points to undo the science investments you have put into a tech line or a fleet. This is a HUGE deal, because now you can safely invest your science in the early game, and if the RNG is "not in your favor" later, or you didn't plan well, or heck your priorities just changed, you can re-spec. This ability to adapt as you go is pretty important, and I'm kind of shocked I never even thought of this prior to now. Hacking points are still a finite thing, so you can't do this endlessly, but they are generally plentiful enough that this won't be too painful of a cost. A number of ships have been updated to be in different technologies now, too, with this release. Without the re-spec ability, this would likely completely break a number of savegames since you might have science committed to places that are now pointless. But these adjusted tech memberships for ships help to make all the techs more balanced and sensible. We are also continuing to finalize the tech descriptions and what techs have new names at all. You also can't swap ship lines out of a fleet you've not fully claimed yet, too. Oh good grief! This release also has the ability to gift fleets and planets between empires in MP. This release has been that long inwork I forgot that was still new. There's a new Ambush Carrier Frigate in the base game, donated by CRCGamer. Astro trains got more exciting. Many mod updates. Major pathfinding improvements for giant games in particular, but it benefits everyone. Many of these features are huge on their own, but almost get lost in this release.
