I am sure I will get beat down for this, but free is free right? So I have to try.
This deal is tor a free Steam Key for the SKIN PACK to the Friday the 13th Killer Puzzle game (THE GAME IS ALREADY FREE). There were no catches or anything, except that you supposedly have to get to level 2 (which I am not sure you need to). I tried it. It is actually kind of addicting.
