Heroes 3 Maps, page 5

In the game, the list of scenarios opens from the main menu when you start a single-scenario game. It sorts maps by size (Small, Medium, Large, and Extra Large) and shows each one's players, victory condition and description, but nothing of what the map holds; a map file placed in the game's Maps folder joins the same list.

Here the game's maps filter by size, players, human players, victory condition, version and underground level, each with its overview, and every map opens on its own page with its objects.
