PIRATES OF CARRIBEAN

(Note : This is more of an exploit than a glitch - Ed) 

Collect 100 Souls - 150 points

Collect one hundred souls from your enemies using the power of the Jackanism sword.

On the Isla Cruces level, either in the story mode or on the replay level mode at the very end of the level, when you are Captain Jack, as soon as you zip down the rope onto the beach, run to the climbing rope opposite. Climb up go into the cave and pull the lever (you will have already done this earlier in the level with Elizabeth)

Change to Elizabeth and go into the cave with the cage door, before it closes. Leave her in there, change to Jack and fight the enemies. Using special moves whenever possible, thus slowly collecting shrunken heads.  When then boss comes from the water, he will run straight over to the cave and stay there. 

Keep using the heads, when you get them to activate the Jackonism sword try and swipe as many enemies as you can, collecting souls. Rinse and repeat the shrunken heads. Also do not activate your sword near grenades or you will die resetting your count. 

Just remember how many you need before you start this. It can take a little while, but be patient. It will work once you have collected enough. Go kill the boss at the cage, kill the a couple more enemies, finish the level and kerching! Hope this helps
