H-I-T-S is his name.
Beat it yesterday morning. Was evil as hell. I had these killer horns, flies buzzing all around me and a wicked blood mist that followed me everywhere I went.
And, just like in the real world, I smacked the crap out of my wife and got divorced. Good times.
Stick around after the credits and you can keep playing after beating it. The only problem is that you're TOO powerful and can just mow down entire towns with ease. Kinda fun, but gets old after a while.
