The Misery 2.1 official version has just released and as usually these guys have delivered. There is a reason it's currently ranked number one at MODDB.
Misery 2.1 is a very popular mod for Stalker Call of Pripyat that is not for the faint of heart. Although a beta version of 2.1 has been out the developers have just announced the final version will be releasing on March 18, 2014.
Love STALKERs series!
