You can read all about it here:
http://arcengames.com/mediawiki/index.php?title=The_Last_Federation_Alpha_Release_Notes#Alpha_Verson_.600Well, you can read about the parts that affect combat, anyway. There were also a metric ton of things in there relating to the larger solar map game, but since there was no prior version of that public, there was no point in noting those differences.
So, what's the TLDR with this version?
1. We're adding 10 new people to the alpha, as part of Phase 0 still.
2. A lot of interfaces and so forth have been greatly improved.
3. Ship balance is crazy improved.
4. Combat is incredibly more involved now, and asymmetric, in the majority of cases. You can fight against multiple fleets at once, they have turrets, you have special abilities, etc.
-- If you want to test a case that is kind of like a lot of game circumstances, give yourself three abilities of your choice, and put in maybe 3 enemy ships as well as 5 constellations and maybe 14 fleets on each enemy ship. That's a fairly stiff fight, but not an unrealistic one, and it's definitely one I'm able to win on Normal difficulty, so I'm curious how you fare.
5. The solar map game is actually NOT released this version, and instead will be tomorrow. I've just been pulled in too many directions today to get that as fully tidied up as I want. We'll add in more testers tomorrow as well.
Side notes:
1. I'm actually not really going to be reading feedback this weekend, but please feel free to log it on mantis like you normally would. I am going to be focused on the metamap, and Josh will keep an eye on mantis for anything that is super-serious breaking the game. But beyond that, we'll be getting into polish and your feedback starting on Monday. Right now I'm just trying to stay laser-focused on the solar map stuff so that you can actually play that part of the game! But at the same time I wanted to get this into your hands so you could check out the new combat on the weekend while you might have more time.
2. I will also try to put out a new combat video tomorrow after the solar map stuff is released, if I have time. If not, then on Monday for sure. I'll also do a video of the solar map stuff.
Enjoy!
