Prince of Persia: Revelations Cheats

Unlimited sand
If you reach a save point, there might be a vase with an extra sand slot. Destroy it to get the sand. Save the game, then fall off a ledge or get killed. Load your saved game and destroy the vase again. This will give you unlimited sand to work with.

Defeating ninjas
You can kill ninjas quite easily by using combo attacks and dual wielding a dagger-like weapon while they are not blocking (after you hit them once). Quickly press [Triangle], [Circle]x2 after their guard is down for a one hit kill.

Defeating women
Killing women is difficult because they always block and you cannot jump over them. To easily kill them, run towards a wall and press [Square]. You will launch off the wall towards the nearest enemy and hit them. This is unblockable, but not undodgeable. This will also knock them down so you can stab them while they are vulnerable and use a combo on them when they get up.
