A mod for the fheroes2 engine
A battle-focused expansion of the open-source Heroes of Might and Magic II engine — hand-crafted tactical duels, six story campaigns, a built-in campaign editor, and browser-based online co-op. No kingdom management. Just the fight.
Built on fheroes2 · requires original HoMM II assets or the free demo data.
What's inside
Everything lives under a new Battle Campaigns hub on the main menu — all of it data-driven, so new content drops in as editable text files with no recompile.
Build-your-own-army puzzles. Beat each fight under a gold budget, a unit-count cap, and a restricted roster.
Six 10-level story gauntlets — one per faction. A fixed army, no hero of your own to lean on, enemies stronger on paper every step.
A full in-game designer. Set both armies per level, terrain, objectives and bosses, then share the campaign as a plain text file.

Each campaign hands you that faction's tier 2–6 upgraded roster at ten weeks of growth, then escalates the odds across ten hand-tuned levels.
A holy order marches into an undead tide — bandits give way to vampires and bone dragons.
Grand Elves and unicorns hold the wood against corrupted beasts and warlock legions.
A warlord binds the rival clans, then wars on a lowland wizard enclave of golems and titans.
Hydras and red dragons burn through the green kingdoms — until a rival Dragon Master answers.
A stolen codex looses the elementals; a Titan-heavy enclave stands against every power at once.
The dead war on the living, from village militia to a crusader church and a grand coalition.
Online Co-op · experimental
No installs, no accounts. The host runs the full engine in their browser and streams the game screen over a peer-to-peer connection; the guest joins with a short room code and sends their input back.
A shared-session co-op experience (both players see the same screen), not competitive hidden-information play. Only the host loads the engine with their own Heroes II data — the guest just streams the picture and needs no game files at all. The persistent, self-hosted P2P build is on the roadmap.
Get the game
What you download here is the engine only — the modded fheroes2 program. It contains none of the original game's data. Two quick steps and you're in.
The engine needs the original Heroes of Might and Magic II data. Pick whichever you already have:
Point the engine at your existing copy — buy it on GOG or the Ubisoft Store. First launch walks you through it.
No copy? The engine includes a script that fetches the officially free HoMM II demo assets — enough to jump straight into the battle modes.
