Collect all the life upgrades to fight the Dark Prince instead of Vizier at the end.
Better Stone Guardian control
When you make it into the City Gardens and have deactivated the Sand Gate, you will encounter a large round sunken arena which is patrolled by four Sand Guards. Speed killed them both with "double kills" then drop down into the arena. You will be confronted by the Stone Guardian, which is really just a different looking Thrall from Prince Of Persia: Warrior Within, which means you will initially deal with him in the same way. When you are in front of him, roll between his legs then attack the back of his ankles. After a only a little of this he will drop to one knee, just like the Thrall. Climb up on his back, just like the Thrall, but this is where the similarities stop. After you have climbed up on his head you will stab your dagger into the back of his neck, which will enable you to steer him like the chariot. As soon as you gain control of him, lead him through the large, closed, wooden door in the arena then through another door in the adjoining room. As he is running, the giant speeds up and this makes it much more difficult to control him. However, if you brush him up against the walls, he slows down to a manageable speed. However, make sure you only brush the walls or he will crash and land on top of you.
Defeating Mahasti
When you meet up with Farah again after the brothel, there will be an intermission sequence in which Mahasti will attack you. Climb up to the save fountain, then down to a platform where Mahasti will be waiting for you. Use whatever fighting tactics desired. If you get knocked off the platform, rewind time and dodge the attack. After awhile you will transform into the Dark Prince, and Mahasti will run away. While chasing her, always run to the right, kill the enemy on the platform in between to fill a sand tank, and heal. When you grab the ledge of the platform Mahasti is on, slow time and jump up. Slash at her until slow time ends and she jumps again. Repeat this until her health is depleted. You will then enter a deadlock that you will have to win. If you lose, Mahasti will jump across the arena, and you will have to try again.
Defeating the Canal Monster
This enemy is like a Thrall from Prince Of Persia: Warrior Within. Start by slashing at its legs and climb on top of it. When you are on top, you can control him. Guide it so that it smashes into the doors. Eventually he will tire out near the end of the canal and the level will be over.
Defeating the giant in the Arena
Run around in a circle avoiding his hands until you find a white crate with steps on it. There should be a dagger hole. Run up and hang on to it, then run to the next one and go over the wall. There is a platform above the giant and it will trigger a speed kill sequence, which must be timed correctly. Repeat this process a second time and you will blind the giant. He will smash part of the arena which will make it more difficult to find the ledge you use to attack him. Run around in a circle until you eventually find it. Do a speed kill sequence, then take him out by slashing his legs which will trigger the final speed kill sequence. If timed correctly, you can defeat him.
Run around him a few times to find a set of brown wooden stairs. Go up the stairs, then when you are on them there will be a location where you can run up and stab your dagger. There will then be another dagger location on your right where you must run to. Then, run onto the wall where the giant opens it for you. There will be another dagger location. You must then run up again, and then on your left will be a platform where you will be able to jump onto the giant and stab him. Repeat this sequence and you will blind him. You can defeat him by cutting his legs when he is blind.
Defeating the Twin Warriors Boss
Right after the room in which you must move the statue of your father down the hall, you will have your second chariot race. At the end of the race, you will run into the sand enemy that you saw in the earlier intermission sequence. His brother will come with his sword and surround you in a ring of fire. Run towards the one with the sword and slash at him with your dagger. He will block it, and after a little bit his brother will slam his axe into the ground. Roll to the side to dodge it, and his axe will become stuck in the ground. Vault over him while his brother with the sword tries to slash at you. If done correctly, you will trigger a speed kill scene where you slash them both down to half health. Repeat this process. When the brother with the axe jumps towards you, roll to the side and get away from him. Only go for the one with the sword. If you fail a speed kill you will get knocked to the ground and lose a lot of health. If you find yourself on the ground, do not try to attack coming up; just roll away to the side.
Defeating the Vizier
When you step into the circular room, the floor will rise up until you are level with the fighting stage. There will be a short intermission sequence, then the fight will start. Immediately after the intermission sequence ends, roll to the side to dodge an attack. Repeatedly roll to the side until the Vizier charges at you. Roll to the side once to dodge it, then charge at him and double slash with your father's sword. He will block the dagger, and any slashes after the second one. After you have hit him twice, roll backwards or to the side to repeat the process. If your attack misses, do not try to attack him until he attacks you again. There will be three times when the Vizier will fly up and throw statues at you. Just keep running left or right until you see the statue, then roll in the same direction to dodge it. After awhile, the Vizier will fly up and crumble one of the walls. The chunks of stone will hover around in a circle around the center of the room. The Vizier should be on the opposite end of the stage. Make your way through, then wall run up the columns behind him. At the top of your wall run, trigger a speed kill to cut one of his wings off. If you make a mistake on the wall run or the speed kill, or the Vizier moves before you can activate the speed kill, just try again. Do not get caught on the edge. If you touch the railing it will hurt you. After a few speed kills and you cut off both of his wings, he will fly up and take the boulders with him. Never stop moving, because he constantly shoots sand attacks at you. Make your way up until you get to a beam. Activate the final speed kill sequence, then kill him.
When the fight begins, immediately roll backwards, then get close to him and block his attack. Attack him quickly because he is a hit and run type Boss. After you hit him a few times he will fly back and try to hit you with a piece of the arena. Get close to him again, blocking his punches, and attack him a few times. He will fly back and try to hit you with two pieces of the arena. Roll to dodge them. Then, attack him again and he will fly back and try to hit you with three pieces of the arena. Get close, block, and attack him again. The Vizier will now blow up part of the arena and there will be blocks going around in circles. Try not to get hit by them, as they can do a lot of damage. Do not rewind time if you get hit; try to conserve your sands for later. The Vizier will now fly to every other column and try to hit you with an energy beam. Dodge and get close. Run up the column behind him, which will trigger a speed kill sequence in mid-air. If timed correctly, you will slice off one of his wings. The Vizier will now try to hurt you by trying to hit you with energy beams. You must get close to him and run up the column behind him, which will trigger another speed kill sequence in mid-air. If timed correctly, you can slice off his other wing. It is easy to predict where he will go because it is every other column. Get close to him for the final time and run up the column behind him. It will trigger the final speed kill sequence, where you will stab him with the sword and the dagger. Once this is done the Vizier will take the pieces that were on the ground and form an obstacle course in the air. Look around with the camera and find a block that is sticking out. Run up the column and rebound to grab it. Make your way to the top. Conserve your sands because the Vizier will try to hit you in mid-air, and if you get hit it is a long way down. Use slow time to help you. When you get to the top you will become level with the Vizier. Jump towards him to trigger a Matrix-style sequence. Wait for the dagger to glow and time it correctly to defeat him. You will stab him and you will both fall. After the intermission sequence, the Dark Prince will take you to a dream world where the walls and platforms are yellow and black, and everything is glowing and moving. Pursue the Dark Prince and slash him every time. You are safe in this world because if you fall you are returned to the platform from which you fell. Get to the end where you will see Farah telling you to wake up and come into the light. The Dark Prince will be next to you. Do not bother attacking him because he will make two more copies of himself. Walk into the light to complete the game.
Health bonuses
Shortly after your first transformation into the Dark Prince, you will find a hallway with two paths. One is down a trapped corridor, and the other is hidden behind a cloth doorway. Go through the doorway and follow the beams until you reach a fountain. Drink from the fountain and you will appear in a trapped corridor. Get past the traps to the light, and you will appear back at the fountain with a health bonus.
There is a circular water-filled room shortly after one of your Dark Prince transformations. After solving the puzzle, run up the wall to get to the rods, then jump up from rod to rod. Around halfway up the room you will see a hole in the wall poorly concealed behind a blue banner. Jump through this hole to get to a life upgrade fountain. Make it to the end of the corridor and you will appear back at the bottom of the room.
Right after you defeat the Canal Monster, there will be a fountain where you can save. Go back where you will find some pots and jars and smash them. There will be a hole behind them, which you need to roll under. This will lead you to a bonus health fountain.
After the third Boss fight and a Dark Prince transformation, you will be in a large room with an elevator in it. Make your way up the room until you get to a platform with two seductresses on it. Defeat them, climb over the railing, then jump up the dagger holds. At the top one, do a wall jump until you activate the pressure plate. Slow time and go through the door on the left before it closes. At the end of this hallway there will be a health bonus fountain.
After the intermission sequence in which Farah kills a Sand Guard for you, climb the rooftops and kill the Sand Archers in your path. After a while you will be told that you have lost the rooftops. Make your way down until you are in a room with one of those mechanisms that you stab your dagger into. It will open two doors. Do not go through the closer one to your right. Go through the one behind you down the ramp. Go through the corridor until you get to a health bonus fountain.
Get past the second tower climb, where you raise stone blocks in elevators when you are at the top. Go inside to see a corridor with traps and diagonal jumping shutters. Go back outside, then go down to the last platform you were on. You will see that you have the landscape view option available. Use it and go into the doorway you see below. It will lead to the last extra health fountain. Note: The traps in this area are difficult. It is frustrating, but you can do it without any slow downs. Do not worry about falling; you will wake up on the floor in front of the fountain and can try again.
Infinite sand
A lot of the secondary weapons have special powers. Some, like the Illusions Dagger, are instant kills if thrown and not blocked. Some will knock an opponent down with one hit, like the axes you get from the weapons racks. However, the most important secondary weapon is the Sand Gate Guard's Sword. At every Sand Gate there is one guard with red armor, who has sand flying to him from the Sand Gate. He is the only guard that can call for reinforcements. If you kill him you only have to deal with the other enemies. Note: All the Sand Gates can be defeated with Speed Kills so that there is no need to fight anyone, but this is difficult. The red Sand Gate Guard drops his sword after you kill him. This sword's power regenerates one Sand Tank approximately every 1.5 seconds. Therefore, as long as you are carrying this sword, you will have virtually unlimited sand, unless you either throw it away or become the Dark Prince. You can regain this sword at any Sand Gate. However, because this sword has a rather low number of hit points, if you want to keep its power do not use it in a fight; just use the dagger and your Sand Powers.

Voice credits
Play through the game until getting to the large courtyard just immediately before the first chariot sequence, during your second Dark Prince transformation. Look in the corner of the courtyard to find a hole in the ceiling which enemies appear from until you leave the area. Stab and hang from the panel near that hole to open the exit. Climb the pole nearest to the hole in the ceiling to hear a monotone female voice announce the game's voice credits.
