Hatred, they got it on a Groupee bundle. You can grab it for around $5!
I have played a lot of horror games, and violent games, but this one really takes the cake. Even after playing it for an hour, it still makes my skin crawl. Only other game to do this to me was Manhunter.
Bundle comes with some music, and some indie-filler /turdware. Hatred is worth the $5 , the rest of the package is pretty bad.
