Prince of Persia: Warrior Within life upgrades and Water Sword: alternate-ending requirements
Quick answer for unlocking the Water Sword and preparing a save for the alternate final battle.
Pictures for this guide
Edition covered
The original 2004 Warrior Within campaign and its two ending routes. Ubisoft Steam screenshots show the PC game. The PSP adaptation Revelations adds areas and is not this route reference.
All nine life upgrades unlock the Water Sword
Collect every life upgrade, then obtain the Water Sword in the Hourglass Chamber before the final confrontation. Merely increasing health partway or carrying the Scorpion Sword does not select the Dahaka finale.
| Condition | Meaning | Action |
|---|---|---|
| Fewer than nine life upgrades | Water Sword requirement is incomplete | Find remaining upgrade routes |
| All nine life upgrades | Water Sword can become available | Return to the Hourglass Chamber |
| Water Sword obtained | Alternate final-battle route is prepared | Carry it into the final sequence |
| Earlier save retained | Both routes remain easier to revisit | Keep it separate from the finale save |
Search upgrade routes before committing to the finale
Life upgrades sit beyond hidden traversal and trap passages around the island. Some routes depend on later movement or weapon access, so keep a checklist and revisit missed areas while backtracking is available.
| Check | Reason | Useful habit |
|---|---|---|
| Hidden breakable wall | Can conceal a side route | Revisit after a stronger sword |
| Timed switch passage | May lead to a trap corridor | Trace the route before triggering |
| Past versus present | Access differs between periods | Record the period beside each find |
| Upgrade fountain reached | Confirms that route’s reward | Mark it collected immediately |
Separate sword availability from carrying it
The upgrade requirement makes the sword available; the Prince still needs to take it. Keep a save before the final route if you want to compare the two endings without replaying the campaign.
Use the final save to verify the loadout
Spoilers: the Water Sword route leads to the Dahaka battle. Confirm all upgrades and the equipped sword before leaving the accessible part of the island for the ending sequence.
