Reinventing the CraftA project that aims to add more functionality to Warcraft III, while at the same time keeping it a low size, so it's still useful for mappers. RtC will be available for any type of map, mod or even a Total Conversion.
The video you posted has nothing to do with this project, it's 1 year old while our FPS thing only started a month ago.
But yeah, with our mouse natives you are able to create something like that yourself. Mindy is working on a tutorial on the subject so stay tuned.
