Say the words 'Ornstein and Smough' to anyone who has ever completed Dark Souls. Watch their body language shift. Twitches, facial tics, full grown regressions, rocking back and forth in the foetal position: these are some of the reactions you can expect. The Ornstein and Smough boss battle is balls to the wall difficult. It has broken many a human being, and now it's been remade in Starcraft 2.
Some enterprising modder has made them the very first boss in a Starcraft mod he's making. His name is Greythepirate and he is obviously a glutton for punishment.
All the details of the boss fight are present and correct. There's the big chubby bastard Smough and the smaller, but lightning quick Ornstein. Once you've killed one of the buggers, the survivor ingests the power of the dead one and becomes more powerful, just to mess with you. The same goes in the Starcraft 2 version -- a very neat little homage.
It's very cool indeed. Dark Souls players will definitely appreciate this.
