Tomb

A tomb is both a lot assignment in Edit Town and the Create a World tool, and also any lot that contains tomb objects acting together to make a puzzling adventure.

Lot assignment
There are two kinds of tomb lot assignments in Edit Town and Create a World, Tomb and Hidden Tomb. These assignments are locked from use outside of the The Sims 3: World Adventures sub-neighborhoods in-game. The tomb lot assignment generates a tomb map tag, and it attracts explorer NPCs. The lot assignement does not generate the moodlets players will see in tombs, these are instead generated by the tomb fogger tomb object.

Puzzles
Tomb puzzles are defined by setting the tomb fogger object to 'final room' and giving the tomb a name. There can be multiple tombs on any kind of lot type, including residential lots.

Tombs are often underground labyrinths that hold puzzles, traps and treasure. Tombs can be found in Shang Simla, Al Simhara and Champs Les Sims.

Tombs can be a place of suspense and discovery. Unlike common buildings, unexplored areas of a tomb are often fogged out as Sims explore new tombs. Once a Sim enters/sees into an unexplored area, the fog of the room fades away, and a sound effect plays.

'The following are lots assigned as tombs in the sub-neighborhoods of The Sims 3: World Adventures'' expansion pack. This list does not include residential lots, art galleries nectaries, or markets that contain tomb objects.'''

Tomb of Discovery
The Tomb of Discovery is the first tomb most adventurers will explore when they arrive in Al Simhara. It has very simple traps, and acts as an introduction to various tomb objects.

Mastaba Ruins
Mastaba Ruins is nothing more than a hidden short cut that can get Sims to and from the Pyramid of the Sky faster than going around the coast.

Small Oasis
The Small Oasis is an entirely empty lot hidden above the Ship's Oasis. It may have been cut due to deadline pressures.

Unnamed orchard lot
The unnamed orchard is where Sims can harvest some decent quality rare fruits in Al Simhara.

Forgotten Burial Mound
The Forgotten Burial Mound features a number of small tomb puzzles, and is central to some adventures in Champs Les Sims.

Chateau du Landgraab
The Chateau du Landgraab is the primary tomb lot in Champs Les Sims. It used to be inhabited by the famous Admiral Landgraab, and possibly other Sims as well because it has several bedrooms and a nursery. It includes two double-bed bedrooms, a bedroom with two single beds, a private study, private library, kitchen, several bathrooms, and many relics and treasure chests. Because Landgraab was a worrywart and obsessed with military code, the place is dotted with traps.

The Little Island
The Little Island can only be accessed by zenoportation, or the Teleportation Pad because it sits in the middle of a river. It features a large tomb puzzle leading to money trees and relics.

Shang Simla tomb lots
The Hot Springs and Abandoned Barn are not tomb lots, they are tombs built on park lots.

The Dragon's Maw
Since it first appeared in promotional material, The Dragon's Maw has been one of the most intriguing lots in The Sims 3: World Adventures. Not only does is have an impressive carved dragon's head, but a mysterious fog also periodically drifts out of the head's mouth. It contains a tomb, entered through the mouth, and is the centre of several adventures.

Dragon Springs
The Dragon Springs does not contain a tomb, even though it is a tomb lot. Instead it is a landmark in Shang Simla, and the only place in the game where Sims can catch the rare dragon fish. It features a The Water Breathing Dragon statute prominently.

Halls of the Lost Army
The tomb inside the Halls of the Lost Army is the first tomb most players will explore in Shang Simla. It features a simple tomb, and attracts many explorers.

Resolute Fist Retreat
The Resolute Fist Retreat has beds and Martial Arts training objects, so that it looks like an academy with a tomb map tag. However, it has an extensive tomb in its basement.

The Temple of Heaven
The Temple of Heaven sits high above Shang Simla, and contains several tombs, including the tomb that leads to Pangu's Axe.

The Terracotta Army
The Terracotta Army is based directly off the Terracotta Army (兵马俑) in China. There is a tomb beneath this lot.

Crane Master Martial Arts Park
Crane Master Martial Arts Park is a hidden tomb, but it has no tomb objects on it. It does have Martial Arts training equipment like the Sheng Hai Training Dummy. It also has a great view of Shang Simla.

East, North, South, and West Towers
East, North, South and West Towers are all hidden tombs. They are clones of each other, and contain nothing of note.

Han's Barn
Han's Barn is a hidden tomb, but it contains no tomb objects, nor anything else of use. It is just there to add flavour to the area. It is clearly related to Han's Orchard.
