In general, yes. I did play most of them in Orbis and it was fun. Especially Khazad in Against the wall - workable mountains and Ironbreaker unit...just a small question... do the FFH scenarios work in Orbis? I mush prefer it that normal FFH but don't want to waste time trying one only to find out that it is broken towards the end.
I can't guarantee they are bug-free. Orbis (and FfH) are not anyway.
There are many changes in Orbis and I could not test whole scenarios after every update.
But if you do find anything, I will try to fix it ASAP.
