Multi-Heroes?

[Stavis_L]

Hey all,

I've seen several comments lately about "multi-heroes" (vs. the more traditional unique heroes), and I (to my knowledge) haven't seen one in the (SP only) games I've played. I gather that they are nation specific, and I was wondering about them (in case I would like to see some pop up.) I didn't see any detailed explanations in the FAQs, strategy guide, or the manual about them.

Basically, I'd like to know:

1) Which nations have them?
2) Are they based on the nations normal units, or are there special "hero chassis" units? If they're the normal units, are any of the nation's commander units potential multi-heros?
3) Depending on the answer to the above, does each nation get a particular multi-hero chassis, and all multi-heroes are based off of it, or do some nations have multiple multi-hero options?
4) Can you get multiples of the same "type" of multi-hero a) in the same game, b) at once? (thinking they might be something like the demon lords, where you can re-summon, but not have dupes)
5) Is the chance to get them affected by luck scales just like unique heroes?
6) Anything else interesting about them?

Thanks!
