Cover system?

I ve found on the internet a really interesting tutorial. Rather than a tutorial it is the script files for a cover system. I always wanted to implement a proper cover system in a first person game and see how it looks. I always have been willing to try to make one that actually work, different from what I ve seen until now in all the games I ve ever played. As said, it would be really interested, but I ll leave it for the end, as an extra because for the moment it is not essential for my game.  Anyway, ill try it, later on.
