It's like the Prince is infected with this disease that turns him into a chain wielding psychopath. That's basically what Ubi was trying to convey to us just recently during a demonstration of the still un-subtitled Prince of Persia 3 at this year's Leipzig Games Convention. After returning home to Babylon with his girl Kaileena (the Empress of Time Prince saved in an alternate Warrior Within ending), our royal boy discovers an enemy at his gates. Somehow this leads to Kaileena dying. Since she basically serves as a containment vessel for the Sands of Time, they get loose. Specifically, they ravage the Prince's people, contaminate his generals and eventually curl all the way up his arm, stopping just below the neck. City burnt? Check. Girlfriend dead? Check. Sand crap eating away at arm? Check. But the worst part is that when the Prince gets emotionally distraught or charged or unbalanced, the Sands of Time infection can take control and the Prince will transform into the Dark Prince. The Dark Prince used to look like a Wraith from Atlantis (one of those white-haired vampires), but now he's been altered to more closely resemble a creature infected with the Sands. Fans of the series that have been reading up on Prince 3 might notice that the transformation was not always going to be handled like this. Ubi used to have the Prince shifting into his darker half whenever fire was involved, but now it's apparently also happening as part of storyline scripts. Though, water does still act to calm the Prince down and soothe his Sands of Time disease. While each version of the Prince has a different move set, both share the basics (jumping, running on walls, slashing, etcetera). In fact, little seems to have been changed in the platforming department since our last checkup after E3, but the speed kill system has been seriously modified. Sneaking up on someone and striking them unawares used to result in the immediate death of the enemy, now it triggers an almost Genji-like slow motion routine during which time a specific prompt will appear. If you manage to strike down your opponent within this window of opportunity, you'll kill and he'll die. If you fail, you may incur a health penalty (like getting stabbed in the belly). Funny how the speed kill system now uses slow motion, eh? The new speed kills are being pumped into boss fights, too. The general without a lower jaw we've been seeing in screenshots has to be mounted and speed killed to be beaten, but even then it's not just a single hit you need to do, it's a combination that has to be performed. Break the routine and you'll end up dead yourself. That about sums up the dark and light side of the princes let the battle begin
