Hello there,

There is a mod for cs:go coming out on the 25th of december.
It's aim is to bring together the feel from 1.6 with the improvements from cs:go.

Check it out here:

Some people think it's a useless project, some people hope it can bring the oldfags from 1.6 back to a newer game along with the new players...time will tell.
