New beta build! https://wiki.arcengames.com/index.php?title=AI_War_2:Multiplayer_Alpha_And_Beta#Beta_2.756_Choice_OF_Injury
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.
Right now the most_recent_stable_beta points to 2.753 still, because both last builds were not great. There were some invincible ships happening in the last build, but that's fixed now.
More exciting is the new stuff. The way that ship crippling works is finally revamped, like I've been talking about for a week or so. Essentially, all of the new mechanics are optional, though; you can turn literally all of them off, and make crippling just be "it doesn't work until it's repaired back to full health." By default, though, it uses the most friendly version of the new "bail out" system (Trigger On!) to warp the crippled ship back to the nearest friendly space. It also costs more to repair until it is no longer crippled (which means 100% health now, not 10%), but it's not in a way that should bankrupt your metal. And that can be tuned. It also now costs you a few hacking points when ships get crippled; more for bigger stuff. Again that can be turned off or tuned. We wanted a variety of consequences, to have people avoid getting crippled carelessly if possible, but not to the point where people want to reload saves.
Superterminal and Dark Spire VG hacks should be way more tame now. They were too rough.
Citadels have gotten a rework, being more cheap (in AIP) and more effective in some ways, but not coming with built in turrets to start with.
Forcefield harmonics let certain very large ships fly through enemy forcefields as if they are not there, but they still can't fire at the ships under them.
If you scrap some units on planets that are friendly to you, you get back a percentage of the metal now. 15% by default, but you can customize.
Enjoy!
