Execution Ground:

Go around the corner and loot the vase and two pots.

A short scene will play, starring Mr. Alligator.

Proceed and loot the contents of a vase.

Two more vases can be found at the end of another jetty, and another two are at the east end of the jetty.

A group of Majini's will attack you, including bowmen that fire arrows with explosives attached to them at you. One of them is in the left (northeast) outpost.

Kill the Majini's and head to the right (south) side of the area.

More Majini's assault you, including a few more bowmen. Kill them.

Have one of you stand next to the crank. The other should go to the raft at the south-east of the area.

Your partner should rotate the crank as fast as possible, while the other dodges several bites of the alligator while on the raft.

The dodge command is R1+L1 on the PS3, and RT+LT for the Xbox 360 version. If you're playing on Veteran or Professional Mode, it can either be the aforementioned command, but also Square + X on the PS3, and X+A for the Xbox 360.

Quickly get off the raft and kick the button to unlock the door.

Exit the area by going over the lowered bridge.

Go through the cave tunnel, shoot the first torch to secure a Ruby (Pear).

Shoot the second torch in order to find a Sapphire (Square).

Back outside, search the grass on both sides for two Small Golds, but beware of snakes.

The left tent houses a First Aid Spray.

You can find two Wooden Barrels behind the tents.

There's also a BSAA Emblem between the tents.

Inspect the oil barrels to find a Jewel Beetle.

Search the grass north of the oil barrels for more Small Golds.

An Incendiary Grenade lies near the entrance of one of the tents.

Continue north and loot two Wooden Barrels from the cabin.

Make your way towards the refinery.

Check your right for a Square Ruby.
