The higher difficulty quest will be available at the Guild Hall, in addition to normal and upper class quests available from Monster Hunter Portable 2nd (MHP 2nd).
New Village Elder
It was an old man in Monster Hunter Portable, an old woman in MHP 2nd and now the village elder is the well loved Ailu? Hunters can now take on upper class quests from the new village elder, they were only available at the Guild Hall previously.
Hunters can now bring along an Ailu for their dangerous trips in the wild. Called “Otomoail” (translation via neoGAF), the white colored cat is only available for single player missions, but just imagine if it’s in the multi-player missions as well, total chaos :) Otomoail has its own weapons and armors, one of the screens show the cat carrying a bomb…
Possibly the star of the game, and not unlike Tigarex in MHP 2nd.
This thing float in the air, and it looks really scary to me.
Daimyou Zazami Sub-species
It gave me a lot of troubles when I first meet it in MHP 2nd, but I think it’s one of the easiest monsters to deal with later. Will the sub-species has new moves or is it just a longer health bar?
The new (and I hope it’s not the only) map. Other new maps mentioned were from the earlier games in the series.
