46%!
I took advantage of the vastly superior skirmish forces to capture most of the points early, without taking command of any ship to start. After early map control was secured, I called in the heavy ships and hopped in to the Astral myself, keeping it near the action, shooting down incoming missiles and constantly refitting the two torpedo bomber wings as they went on non-stop attack runs against the Onslaughts.
Didn't do much micro, and consequently most of the Wasp wings died on suicide runs as I set them to search and destroy. Ah, well, they're drones for a reason. In the full game, losing those won't actually kill the pilots.
One of the Tempests managed to limp through the battle, along with a Dagger wing, one Conquest, and one Apogee - as well as the Astral, of course.
Nice work, that was great fun
Hadn't seen that many large ships in action at once for a long time.
As an aside, I'd base the difficulty label on how hard it is to simply *win*. Getting 100% is almost impossible in any sufficiently large battle because it requires 1) you lose nothing, not even a fighter wing; and 2) that nothing escapes. In my personal opinion, this is a real "medium" mission (as opposed to the "haha it says it's medium but it's actually hard" Hornet's Nest).
Also, this makes me think the Onslaught AI isn't aggressive enough. At one point they had both Nav Buoys and still didn't press the attack, content to trade long range salvos in a losing effort. But then, you've already pointed this out in an earlier post. That shouldn't be too hard to fix up, to be honest - the AI already knows *how* to be aggressive, it just sees all the LRMs and decides to duke it out from range.
