Prince of Persia: Warrior Within Cheats

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 clock tower 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.

1 (Past): After fighting the girl in black a second time, pull the large altar on ground level of the sacrificial chamber to reveal a secret door. Go through the trapped hallway and get the first Life Upgrade.
2 (Past): This is done after Slow Time is earned. From the room where the Prince has an intermission sequence with the maggot man creature, go into the large courtyard-like room with a timed floor switch next to some stairs. This switch opens a low gate at the top of the same set of stairs. Go through that trapped hallway for the second Life Upgrade. Note: To obtain the second Life Upgrade without getting the power that slows time, you must find the switch behind the barrels. Press the switch and wall ride up the wall, instead of running up the stairs roll. If done correctly, you should make it a moment before the door closes.
3 (Past): This is done after the Serpent Sword is earned. Rotate the turnstile switch directly opposite the facing of the metal nub where the Serpent Sword was used to create platforms to a door at the bottom of the chasm. Use long wall jumping to slow the Prince's descent down to the level of the door. Past that door is a trapped hallway that leads to the third Life Upgrade.
4 (Past): When exploring the Garden Tower, look for a room that is overgrown with vegetation and is directly below a box and folding bridge puzzle. It is in the same vicinity as the first switch that turns on the water for the Garden Tower. A break in the fencing allows the Prince to drop off and use ledges to access a door underneath the overgrown vegetation room. The fourth Life Upgrade is past that trapped hallway.
5 (Past): When exploring the Garden Tower's second water puzzle, ledge up after turning on the water (but before exiting the room with the turn switch) for the fifth Life Upgrade.
6 (Past): When exploring the Clock Tower, look the giant Golem enemy that throws explosives. One breakable wall is a save point, but there is a second breakable wall on the other end of the room leads to the sixth Life Upgrade.
7 (Past): After gaining the Scorpion Sword and a particularly tough giant Golem encounter, a ladder leads the Prince to a Roman courtyard room. Two breakable walls are here -- one has a switch, and the other has the door which requires Slow Time to access. The seventh Life Upgrade is past that door.
8 (Past): After entering the Library, the Prince will need to pull out two bookcases to continue his progress. Look for two circular ledge/beam structures (one of which will have a Ninja) after dealing with the bookcases. One of the circular ledge/beam structures leads to a wall with three levels of ledges that may be climbed/sidled. This is a detour to the eighth Life Upgrade.
9 (Past): There is a location near the beginning where you chased Shadee (girl in black) and a door shut behind her. You then have to go up a set of platforms to finally reach the switch atop the room, just before sacrificial pit. Go back there when you get a sword that can break walls. Make your way back up this room. Look carefully when on the top platforms. There should be a set of metal bars in one of the wall that seem damaged. There is a crate behind those bars. Break the metal bars with your sword. Bring the crate onto the platform and look up. You can use the crate to access a passage in the roof to reach the ninth Life Upgrade.

To get this weapon you'll need a sword that can break walls. In the Mechanical Pit (Present), go to the room with the fireplace at the top of the pit, where you once fought a Brute. At the back of the room there's a passageway that bends to the right and dead-ends at a water pit. Drop into the pit and you should see a section of wall with light shining through it. Break this wall to expose a weapon rack. Break the rack and you'll be able to pick up the Teddy Bear, an unbreakable secondary weapon that does minimal damage, but restores some health to you every time you hit an enemy with it.

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.
