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 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.
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.
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.
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.
