This is a wickedly difficult game, featuring levels and enemies designed for one purpose: to kill you as quickly and mercilessly as possible. The game is so vengeful that there is even a sinister laugh to taunt you every time you die. Make no mistake, this title is not for the casual or even the mainstream gamer; it is purely a hardcore-only affair. However, if you fall into this camp of gamer, someone who craves insane difficulty and a nearly endless experience, then you'll want to pick up this one right away."
