Dear dotamods.ovh visitors,
we want to inform you that all the mods beyond this post is for Source 1 Dota 2. It means that after September 2015 they do not work! Mods working in Dota 2 Reborn are above this post.
We are working hard to gather updated versions of the older mods, but it will take time.
We do listen to your feedback. We are also using this opportunity to update and change the website, to make it better, faster, stronger. GL & HF.
