Heroes of Might and Magic III Remake Campaign Guide

Heroes of Might and Magic III Remake is not a new plot. It is Restoration of Erathia, Armageddon’s Blade, and The Shadow of Death played as one continuous experience, framed by a new prologue, a new epilogue, and a set of fully produced cinematics. This page is a structural walkthrough: what you play, in what order, and which systems each act is trying to teach. Individual mission maps still belong to the original designers; we are not rewriting every win condition from memory as if a retail script had shipped.

The new prologue

Preview sessions describe a three-mission prelude. Geek Culture played a section called The Queen’s Departure. Dualshockers sat through about twenty minutes of an intro that covered combat, recruiting, spells, towns, and fog of war. Rock Paper Shotgun says the prelude exists to teach systems before you drop into the original campaign. That is the entire point. Do not treat it as skippable flavour. The remake’s camera, town queue, and recruiting UI are introduced here. If you skip it, you will fight the interface during the first real mission instead of fighting the AI.

Catherine Ironfist remains the human face of the opening war. The king of Erathia is dead, neighbouring powers move on the corpse of the kingdom, and you are asked to restore order. The reveal trailer is that thesis in ninety seconds. The campaign is that thesis stretched across dozens of maps.

Restoration of Erathia

The original 1999 campaign is the war for Erathia: Castle and its allies against Necropolis, Dungeon, Inferno, and the rest of the board as scripts demand. You will rotate viewpoints. Heroes III campaigns were never one hero from mission one to the credits; they were a relay of scenarios with carry-over heroes, banned heroes, and starting bonuses that punish you for ignoring the briefing.

Practical advice that still applies:

• Read the scenario description. If it says you cannot rebuild a town, believe it.
• Carry-over artifacts and levels are a resource. Do not suicide a starting army for a side mine if the next map needs that hero alive.
• Difficulty in the original spiked when the script handed the AI extra towns. The remake has not announced a rebalance of those scripts. Play the first map of each act as a scout, not as a speedrun.

Pair this act with the Castle and Rampart write-ups because the early human and elven viewpoints are where new players live. When the viewpoint shifts to Necropolis, stop playing as if you were still a knight.

Armageddon’s Blade

The first expansion is the Conflux war: Lucifer Kreegan wants a weapon that can burn the world, and Queen Catherine plus new allies have to stop the forging of Armageddon’s Blade. This is where the ninth faction, Conflux, belongs. The 2015 HD Edition never included this campaign. The remake does, on day one, which is the single biggest content argument against buying HD Edition as a substitute.

Conflux armies are magic-heavy, with elementals and Phoenixes, and they play differently from Castle’s grind. If this is your first time in the expansion, open the faction overview before the second Conflux map, not after you already built the wrong Mage Guild path. The creature tier list will argue about Phoenixes; this page only needs you to respect fire magic and elemental immunities.

The Shadow of Death

The second expansion is a prequel in original chronology: Sandro the Necromancer, Gelu, Yog, Gem, and the assembly of cursed artifacts. The remake’s marketing specifically calls out Sandro’s ambitions alongside Catherine and the Blade. In a unified saga with a new prologue and epilogue, expect connecting cinematics rather than a complete rewrite of mission order. If Ubisoft changes sequence, this page will follow the retail menu, not 1999 box order.

Shadow of Death maps are often puzzle-like. Heroes start in awkward corners. Necromancy and Diplomacy both have scenarios that assume you know those skills. If you arrived from the beginner guide and this is your first Heroes campaign ever, finish Restoration and the prologue first. Shadow of Death is a poor tutorial.

How to actually beat a campaign map

The how to play loop still wins missions: mines, second hero, weekly growth, a core stack, then the enemy towns. Campaign maps add scripts. Some maps spawn extra armies on a timer. Some maps hide the win condition behind a seer quest. Visit every red cross on the minimap. If a seer hut asks for an artifact you sold, you have already lost a week.

Difficulty advice: play on a setting that lets you learn the new camera, then raise it. The remake is not trying to be a different balance game. If a map felt unfair in 1999, it will probably feel unfair in 2027, with prettier lighting.

When you are done with story and want endless maps, that is the random generator and the community hub. Campaign is the on-ramp. Random maps are the hobby.
