Modder Retera recently shared that Blizzard contacted him asking to remove his alternative engine for Warcraft III Warsmash from public access.
On July 3, 2022, the day of the 20th anniversary of Warcraft III, modder Retera, the developer of an alternative engine for Warcraft III, Warsmash, posted a video statement revealing that Blizzard demanded that he stop creating the project and remove it from public access.
According to Retera, the Warsmash project was made to create an alternative Java 8 engine for Warcraft III, which significantly expanded modders' capabilities. The project was not monetized and was distributed as open source under the MIT license. All the necessary assets were indeed taken from the game, but to run the engine, users were required to have a licensed copy of Warcraft III.
However, according to Blizzard's letter to the developer, the company believes that Warsmash violated its copyrights, practically copying the original strategy. Blizzard stated that the creator of the modification must cease the project and remove it from public access within 17 days from the date when the modder received the letter. If this does not happen, the company said it will take appropriate legal action.
The Warsmash developer joked that he did not expect such a "gift" from Blizzard for the 20th anniversary of Warcraft III. He did not specify whether he plans to abandon the development of the engine. However, Warsmash is no longer available on GitHub as well as the video statement was removed from the modder's channel.
