The Prince's relief at being spared another fatal plunge, even if it squashes his pride just a tad, is well justified in Epilogue. Crumbling, daunting, dark and no more practical than most video game locales, the Underground Palace is the sort of place that makes you glad you invested in that magical, life-saving companion. Its entirely linear layout offers a breathless string of platforming challenges for the Prince, a final chicane of scurrying and swinging that requires more adept timing than anything else in the main game.
That isn't to say that the downloadable extension is a mere taunt directed at those who scoffed at Prince of Persia's forgiving nature. The difficulty curve matches the dire situation crafted by the story, which has prompted the acrobatic duo to flee rather than fight. It's easy for me to recommend Epilogue based on the engaging spatial puzzles or the elaborate, corruption-riddled platforming sequences, but the real draw is witnessing the aftermath of Prince of Persia's poignant climax.
