Simultaneous Turns – Horn of the Abyss / HD+ mod

Simultaneous Turns (ST) in a multiplayer game allows the players to make their turns simultaneously during a certain time period that significantly decreases gaming time. A host can activate the ST feature when starting/loading a game in “More options” HD+ where you can also set exact day (days in the game) till what day (including) the simultaneous turn is working.

HD mod for Heroes 3 Complete
Heroes 3 Complete GOG version (works only with this version)

Simultaneous Turns can be interrupted if both players interacted with the same objects; the game checks on it after both of them finish their turns. If it happens, both players receive a notification and the blue player must replay its last day.

ST is interrupted if the players start interacting with each other (the game checks on it right in the game process). If the players try to attack/capture each other’s hero, town or mine, then the last blue player’s turn is cancelled and it goes back to the last red player’s turn. The red player continues its turn and if he decides to attack the blue player, the blue one accepts the battle.

During the ST, auto-save only saves the game after both players have finished their turns.
The game can be downloaded from any gaming day and continued without the ST feature. You can also download any saved game where the ST was off, and continue playing with the ST on.
If Turn Timer option is on, then, during the ST, players can see both his/her and the opponent’s timer.

      No, you have to continue with the classic turn mode.

    Hi I recently had an issue with this mode, whenever I’m playing with my buddy online using simultaneous turns it can automatically turn off without a reason despite the fact that A: our heroes were not nearby each other, B: we did not interact with any objects that we previously attended, C: our number of turns set in the menu were set to (1127 – automatically set) and once loaded again we set it to 997. Is this any sort of a bug ? I honestly love hota when it comes to saving time.

      Hi Tex, unfortunately, I don’t have much experience with multiplayer, but try to set the time to shorter, e.g.227. (997 = Month: 9, Week: 9?month is only 4 weeks, Days: 7).
