Two players, one browser tab each

Fight a battle online Work in progress

One of you opens the game and is given a six-character code. The other types it in — or opens the invite link — and lands in the same battle, wherever they are. Neither of you downloads this mod, and neither of you installs anything.

This mode is still being built and is not finished. Expect rough edges: connections that fail to establish, sound that does not always come through, and battles that need starting over. It is here to try out and to report back on, not to rely on.

The host needs

One of you runs the actual game, so that person supplies the Heroes II data — once, from their own machine.

  • A desktop browser; Chrome and Edge handle the folder picker best
  • Their own copy of Heroes II — the folder that contains DATA, about 40 MB. What that means
  • To pick that folder once. It is stored in that browser and is never uploaded anywhere
  • To leave the tab open for as long as you play
🎮

The guest needs

Nothing at all. No download, no game files, no account, not even a copy of Heroes II.

  • A browser, on more or less any device
  • The six-character code, or the invite link
  • You see the host's game as a live stream, with sound, and play your own side by clicking straight into it
  1. One of you hosts. Open the browser version and point it at your Heroes II folder, once. It stays in that browser and is never uploaded.
  2. Share the six-character code — or the invite link beside it, which saves the typing. Rooms are short-lived: a code lasts about fifteen minutes, and the host's tab waits three.
  3. The other one joins. A small rendezvous endpoint on this site is what introduces the two browsers to each other; after that the picture, the sound and the clicks travel directly between you.
  4. Pick the armies, then fight. Outside a battle the host can hand the mouse over so their opponent builds their own army, and take it back at any time. In battle, only the player whose turn it is can click.

Worth knowing before you start

What this is, and what it is not

It is a shared screen

You both see the same picture — including each other's spellbook and army. It is built for playing with someone you know, not for blind competitive play.

Battles only

A single battle, with a rematch after each one. The adventure map and the campaigns stay single-player — those are the browser version and the download.

Some networks will not connect

The two browsers are introduced by a small endpoint on this site and then talk directly. Finding that direct path uses STUN alone, so strict company networks and some mobile ones will not get through at all.

Your files stay yours

The host's game data is read in their own browser and never leaves the machine. What travels is the picture, the sound and the clicks.

Unfinished — see above. Nothing is installed on either side.
