Unblock elements in Metal Gear Solid: Peace Walker

To reach the island of monsters and unlock hunts for Monster Hunter:

Listen first of all the evidence Chico on tapes and then go to the Extra Ops 29. Once there, go back to the beach. Here you approaching from the sea and you see a cat in a boat. Talk to him and he will tell you the position of the island. Make sure you have completed the first mission 29, otherwise the cat will not be present. You can then access these hunts through the usual menu Extra Ops.
