It's possible to watch replays. It works without any kind of program or file manipulation, so you will definetly stay on the safe side.

How does it work?

Starting a replay works in a way that you throw a parameter with a replay link towards the game and the game decides to load the replay file.

First, you need a way to deliver the parameter. To do that, create a shortcut of the "HeroesSwitcher.exe". It is located in the "Support" folder of Heroes' installation directory. It does not matter where you place the new shortcut.

Now you require a full path to one of your replay files. You can find your own replays at:

C:UsersABCnameDEFDocumentsHeroes of the StormAccounts123numbers45698-Hero-1-123moreNumbers456ReplaysUnsavedMultiplayer

So, just navigate to a replay and copy paste its path.

Open the properties window of your shortcut. There you will add the parameter to the "target" line. At first, you will only have the path to "HeroesSwitcher.exe" in the target line. It looks like this: "C:GamesHeroes of the StormSupportHeroesSwitcher.exe"

Now you need to add the following to the end of the path (with a leading space): -run"#" Replace # with the path including the file name. So, you are adding: Space, Minus, r, u, n, Space, ", path to the replay including the file name, "

Now, in the target path you should have something like this:

"C:GamesHeroes of the StormSupportHeroesSwitcher.exe" -run "C:UsersABCnameDEFDocumentsHeroes of the StormAccounts123numbers45698-Hero-1-123moreNumbers456ReplaysUnsavedMultiplayerBlackheart's Bay.StormReplay"

Start Heroes and log into battle.net.

"Alt + Tab" out of the game to return to your desktop. Then start your shortcut and return to the game. It should start loading the specified replay file.

Right now, watching replays is extremly buggy. Since Blizzard didn't add a replay menu into the battle.net UI, it is most likely that the replay feature will receive a complete overhaul. That's why I would suggest that you don't report bugs you encounter until Blizzard adds a replay-starting UI into the game.

The hotkeys are similar to the ones in SC2. So Ctrl+W hides the bottom UI area. Y or Shift+Y (or is it Z?) zooms in/out. In addition to that, it is possible to view the selected talens of the other players.

edit: formatting in reddit is... yeah, is there a way to tell it how much it should include under a single point? It seems impossible to add steps with multiple paragraphs.

요약하자면

1. 히어로즈 폴더안에 heroesSwicher.exe 의 바로가기를 만든다.
2. 만든 단축아이콘의 우클릭-속성 해서 바로 가기텝을 보시면 대상이 있는데 그 뒤에 -run "리플레이 파일 주소"  를 넣는다.
3. 히오스를 실행시키고 만들어둔 바로가기를 실행하면 리플레이가 실행된다.

해보니 잘 됩니다.
