Prince of Persia: Warrior Within HD Cheats

To get the secret ending simply obtain all 9 life upgrades, when you get to the room before the Empress' throne room there will be a new sword waiting for you. It is the water sword and said to be the only thing that can kill the Dahaka. For your final battle, instead of fighting the Empress you fight the Dahaka.
The Dahaka’s attacks are repetitive and predictable. When far away he will shoot his tendrils throw the ground up at you, run around in circles to avoid it making your way ever closer to him. If you get too close he'll shoot out his tendrils directly at you, roll to dodge them. As you roll slow down time and go in for some heavy combo hitting, as you get him lower in health the Empress will help you and shoot him off the arena, he will be stuck on the ledge, stock up on sand tanks (They regenerate around the arena) and slow down time or use Ravages of time to inflict maximum damage. He'll eventually get back up and jump at you, constantly roll until he calms down and remains stationary. Repeat the same method as before until he is defeated.

• Upgrade Pedestal 8: Inside... 

This is located in the Catacombs. Because the Dahaka is chasing you, consider using slow time to escape him. Get to the section where you have to pull three stones out of the wall to raise the central area. After pulling the first, go to the stairway, make a right, run on two walls and jump to the bar on the right side. Swing from the bar and follow the path and make a quick left. The fist is in a weapon rack to the left. The Rayman fist is unbreakable with a high attack rate but does little damage. If you throw it, you lose it forever.

When chased by the Dahaka you can translate his insults by reversing time.

On your second visit to the portal room, when you're required switch the time to the present for the first time, the Prince will say that something is wrong. You must run the switches on the wall to make the portal work correctly. Don't do so. Instead, enter the portal as it is and you will switch the time to the present. Save the game then exit and load the game. You will now be playing as Sandwraith. In this mode you will constantly lose life and much more health when hit than in normal mode. However, your attacks will be very powerful and you'll be faster. Note: Save the game on a different file if you wish to continue the game as the Prince.

After you obtain the Scorpion sword find your way back to the central room. Turn the turnstile so that the lever is facing the doorway with the save point fountain. Stand facing the opposite doorway and walk up a bit and to the right. You will find a ledge that is one step lower than the area around you. Walk down and grab on to it. Jump to the opposite ledge and jump back and forth to slowly make your way down. Once you reach the bottom drop down to the ledge below it. Wall run to the next wall and get ready to jump off and back and forth to make your way up. Wall run again and when you reach the end wall jump to slow your descent once more, you'll eventually grab onto a ledge. Make your way to the doorway that is next to it, but DON'T GO IN. Instead keep going on the rocks until you see the area where sand is falling. With the scorpion sword in hand break the wall. Break the rack of weapons and pick up the hockey stick.
As with all special weapons the hockey stick is unbreakable, but if you throw it you lose it for good. It has moderate damage and a relatively slow attack rate.

The light sword is the most powerful secondary weapon in the game. When in the mystic caves you come upon a door that you must unlock via switch. Directly after that door there is a drop in the floor. Drop down and break the left wall and break the rack to pick up the light sword. As with all secondary weapons it is unbreakable, but if you throw it you lose it for good. The light sword has maximum damage and maximum attack rate.

One of the miscellaneous secondary weapons is the teddy bear. Locate it after earning the Scorpion Sword in the clock (west) tower. There are three encounters with a giant golem enemy in the clocktower when you initially go through it; the first is before you start negotiating the vertical climbing of the tower (past); the second is atop the clock tower (past); the third is is stationary and throws exploding monsters in the clock tower's second area (past).
Look for the room where the second giant golem enemy is. You will need to be in the present (so find a time portal) and drop into the water-filled dead end past the golem's room. Break the wall and retrieve the teddy bear.
The teddy bear is almost unbreakable and does almost no damage, but has the ability to restore lost life to the Prince with each successful blow on an enemy.
