Heroes of Might & Magic III - HD Edition: Complete Guide

A strategy guide to the Steam HD Edition of the 1999 classic: what the HD Edition does and does not include, economy rules of thumb, town-by-town notes, hero skills and spells worth chasing, combat fundamentals, and the campaign outline.

Researched September 2026 — current as of HD Edition Update #4 (the last patch, 2015). The game itself does not change; check the linked sources for series news.

Know what you bought: the HD Edition contains only the original game, The Restoration of Erathia. It does not include the Armageddon's Blade or Shadow of Death expansions: no Conflux town, no combination artifacts, and no random map generator. Most of the community's popular mods (such as Horn of the Abyss) target the Complete edition sold elsewhere, not the HD Edition.

Quick Start

1. Build the Town Hall line early. Gold is the bottleneck for almost everything. A Capitol pays for itself fast.
2. Upgrade the Fort to a Castle in your main town. Creature growth goes up by half with a Citadel and doubles with a Castle.
3. Buy a second (and third) hero. Extra heroes pick up resources, flag mines and ferry troops to the main hero. One big army and several scouts is the classic setup.
4. Flag mines as soon as possible. Wood and ore first, then the rare resource your town needs.
5. Visit stat and skill buildings on the adventure map with your main hero.
6. Recruit every week. Creature dwellings refill on the first day of each week.
7. Don't overextend your main hero. Losing your main army in week 2 usually loses the game.
8. Use the Mage Guild. Early Slow, Haste or Bless decides many fights.

HD Edition Specifics

• Widescreen and high-resolution support, plus updated menus.
• 7 campaign scenarios, around 50 skirmish maps, local multiplayer (hotseat), and a map editor.
• A Steamworks online lobby. Patch #3 added a whisper feature: type your text and press F5-F12 to target players 1-8.
• Patch #3 also fixed mouse lag, missing campaign cutscene music, a Spoils of War campaign bug, an overpowered Lizardmen bug, Charisma bonus totals, and non-Necropolis heroes learning Necromancy on level-up. Patch #4 fixed crashes.

Economy

Resources

Income buildings

Marketplace lets you trade resources; more marketplaces improve the rates. The Resource Silo adds a daily trickle of the town's key resources.

Build order rule of thumb (main town)

1. Days 1-3: whatever gives you a strong week-1 army (usually tier 1-3 dwellings and a Town Hall).
2. Build a City Hall as soon as the requirements are met.
3. Citadel, then Castle, then Capitol.
4. Your top-tier dwelling and its upgrade once the economy can afford it.
5. The Mage Guild levels your main hero's magic school needs.

Don't build everything. A town full of unused buildings is gold not spent on creatures.

Towns

Quick town notes

• Necropolis: Necromancy is the whole plan. Fight many weak neutral stacks to raise Skeletons, and turn Skeletons into Skeleton Warriors.
• Stronghold: the strongest early aggression. Barbarians hit hard but rarely have good magic.
• Castle: very forgiving. Archangels in the late game win many fights by themselves.
• Dungeon: Warlocks are excellent spellcasters; aim for Earth or Air magic.
• Tower: Titans are ranged top-tier units; expensive but strong.

Heroes

Primary stats

Attack, Defense, Spell Power and Knowledge. Might heroes (Knights, Barbarians and so on) favour Attack and Defense; magic heroes favour Spell Power and Knowledge.

Secondary skills worth taking

Often weak: Eagle Eye, Navigation (unless the map is water), Scholar, First Aid and Learning on your main hero. Save your eight skill slots for combat and movement.

Some notable specialists (Restoration of Erathia)

• Sir Mullich (Castle): boosts speed for all his creatures.
• Crag Hack (Stronghold): Offense specialist, a fearsome early hero.
• Solmyr (Tower): Chain Lightning specialist.
• Sandro (Necropolis): Sorcery specialist.
• Tazar (Fortress): Armorer specialist, very durable armies.
• Orrin (Castle): Archery specialist.

Spells That Win Games

Combat Fundamentals

• Speed decides turn order. Faster stacks act first; Haste and Slow change everything.
• Wait and defend. Wait lets a stack act later in the round, which is handy for ranged stacks or baiting. Defend boosts defence for the round.
• Protect shooters. Put melee stacks where they block access to your ranged stacks; a shooter with an enemy next to it can't shoot and has to fight in melee at reduced damage.
• Retaliation: most stacks retaliate once per round. Hit a stack with something cheap first to use up its retaliation, then attack with your best unit.
• Morale and luck can give an extra turn or extra damage. Mixing creatures from different alignments hurts morale.
• Split stacks (single creatures) to soak attacks or block paths, especially against enemies that deal fixed damage.
• Tactics lets the side with the higher skill rearrange units before combat starts.

Adventure Map Tips

• Creature dwellings on the map can be flagged for weekly recruits outside your towns.
• Creature banks and Utopias (Griffin Conservatory, Dwarven Treasury, Dragon Utopia and others) guard big rewards. Check guard strength first.
• Windmills, water wheels and gardens give free resources weekly.
• Learning stones, trees of knowledge and stat shrines are key for your main hero.
• Obelisks reveal the Grail location on maps that have one. The Grail builds a powerful structure in a town.

Campaign Outline (Restoration of Erathia)

The seven campaigns tell the story of Queen Catherine Ironfist returning to Erathia after her father's assassination. Three campaigns (good, evil and neutral) are available from the start; the good and evil lines each continue into a follow-up; Song for the Father closes the main story; and a bonus final campaign unlocks once everything else is done.

Campaign tips:

• Your main hero often carries over between missions, sometimes with capped levels. Invest in them.
• Read the victory conditions. Many missions are timed or require a specific objective, not total conquest.
• Save often and in multiple slots.

Common Mistakes to Avoid

• Expecting expansion content (Conflux, random maps) in the HD Edition.
• Spending gold on buildings you won't use before the Capitol.
• Moving the main army without a scout. Scouts find mines, treasure and danger.
• Leaving the capital undefended against enemy heroes with Town Portal or Dimension Door.
• Losing top-tier stacks to neutrals. Use Slow, blocking and retaliation tricks.
• Filling skill slots with Eagle Eye and Navigation.

Advanced Tips

• Chain heroes: pass the army between heroes on consecutive tiles to move it much farther in one day.
• Hit neutral stacks with ranged units and wait tricks to take zero losses.
• Diplomacy can make neutral creatures join you, a big early army boost.
• Pick fights on day 7. Enemy growth arrives on day 1; beat their army before it refills.
• Plan spell schools. Earth and Air are generally the strongest; a hero with Wisdom plus one of them carries the late game.

FAQ

Does the HD Edition include Armageddon's Blade or Shadow of Death? No. It is only The Restoration of Erathia.

Is there a random map generator? Not in the HD Edition. It came with Shadow of Death, which isn't included.

Can I use Horn of the Abyss or the HD Mod? Those community projects are built for the Complete edition, not the Steam HD Edition. The HD Edition could not include the expansions because their source code was lost, and many reviewers recommend buying the Complete edition (sold on GOG) and adding the community HD Mod instead if you want the expansions, random maps and widescreen together.

Is multiplayer still working? The HD Edition has a Steamworks lobby for online play and local hotseat.

What's the best town for beginners? Castle is the most forgiving. Necropolis is the most snowball-friendly once you understand Necromancy.

Is there a new Heroes game? Heroes of Might and Magic: Olden Era entered Early Access on 30 April 2026. The HD Edition's news feed also posted an announcement titled "Heroes of Might and Magic III Remake" on 26 August 2026.
