Overall, the graphics in the fifth game are garish and inconvenient. It happened more than once that it was difficult to click on an object with the cursor due to the absurd camera angle, and what horrors happen in the Dungeon is known to every player.
That is, the 3D graphics don't impress with their beauty, and at the same time, it's much more convenient to use.
For me, the graphics there are just a set of scary, blurry spots.
Regarding the Orcs:
Probably, they moved from the islands to "Heroes 5" and modernized a bit. That is, there were Papuans on the islands, and then they turned into nomadic Mongols. Although, in the "One Khan, One Clan" mission, the Orcish Clans live on different islands.
Regarding the Dungeon: the screenshot where you can see it is located here.
