Dota 2 Reborn (Source 2) Hack, Now With x64 Support!

What does user script mean? Can I have the explanation about this before i do my subscription here?
there are hake core features and an user script api, where users can write their own scripts or load shared ones from others. the possibilities of user scripts are kind of limitless (from hero scripts, to evade features, to visuals, ...) all we need are some more passionate coders ;)
