Oh, duh, sorry. All champs are AOE immune, not just neinzul.
I could make the AI variants not AOE immune, though.
But that doesn't explain why the Martyrs didn't do anything, so will investigate that, thanks.
Certainly I'd like AI Champions to be not-immune, just so Warheads can be used on them, although I have to ask: why are Human ones AOE immune, anyway?
On a related, but slightly different note:
I'm going to suggest that the alt-progress response be adjusted a little.
I tried it out, with 8 Champions, and since I wanted everything (only available on 9+) I went ahead with Alt-Progress 10. And since Alt-Progress was 10, I set Alt-Response to 10.
For the first 30 minutes of the game, I ran around, did a little exploring, and found an ARS a few hops out. My 8 Frigates were the only Champions in the game.
At 41:00, 34 AI Nemesis frigates invaded and destroyed my Homeworld.
I was rather surprised by this, so I reloaded, and sent my Champions and Fleet out to do a little cleanup. It didn't work. The AI was actually producing Nemesis faster than I could kill them, on the Mk I world next to my homeworld. EACH AI player was spawning a Nemesis every 35 seconds.
So I played around a bit, experimenting with different settings. AI Difficulty 10 *doubled* the Alt-Response, leading to a new Frigate every 18 seconds or so from each AI player. The first wave, 10 minutes after they started spawning, was about 60 Nemesis. Just for comparison, that's almost 4 times the number of Nemesis that a Diff 10 Heroic player sends.
I tried setting up a diff 10 game with NO human champions, but Alt-Response 10. I cheated out the wazoo, and built everything on my Homeworld, then waited. All turrets, all forcefields, all Fortresses, all Mines, Mk IV fleetships, everything. At hour 5, 250 Nemesis and 4000 fleetships attacked (120,000+ strength). The fleetships died en masse to mines and warheads, but the Nemesis just plowed their way across the system, ignoring everything, and killed me. About 100 Nemesis were still left when the Home Command Station went down.
A quick check says a Diff 10-8 Champion-Response 10 game would result in that same 250 Nemesis mob attacking at 1:15 gametime.
I never got to see what a "Nemesis Champion Exo" looked like, because it wouldn't have launched until about 5:30 or so, and I couldn't ever survive that long.
Basically, I'm suggesting that since you cannot access all the Nebula Goodies until Alt-Progress 9+, and (to paraphrase) "set the Alt-Response to at least this intensity" means 9+ response... well, it's a little extreme at the level where you actually try for the equivalent of the traditional experience.
I'd suggest moving the goodies available down quite a bit, so you don't need to go quite so high to get everything. I'd also suggest severely toning down the Alt-Response. Right now, the even the intensity 4 response is much higher then the traditional nemesis response (1 nemesis per 5 minutes, with a cap).
OR, remove all the goodies completely from Alt-Progress, so that Alt impacts nothing but the XP gain rate. Balance that so that Alt-Response intensity 6 or so is equal to the traditional response, and 10 is no more than a diff 10 Heroic AI.
