Miner

The Miner is a new object that is created by a Sim with the Inventing skill and can also randomly be found for sale at the Consignment Store. It can be carried around in a Sim's inventory and placed on home or community lots to begin drilling. Holes drilled in the ground can be used to travel around town from one fully drilled hole to another, although a fair amount of travel time is still required. Players can name their tunnel openings and navigate to them selectively, and can also fill them up again should they no longer require them. In order to create a hole that can be used as a travel tunnel, a Sim must keep on drilling with the Miner until they reach bottom and can no longer drill.

While drilling, there is a chance that a Sim will come across a random gem, a metal, a space rock, some scrap metal or a piece of furniture, along with other miscellaneous items such as Magical Gnomes of Invention. Occasionally, while drilling, a Sim will stop and the hole will glow gold. The hole can then be explored for loot and various moodlets. Having high Athletic skill appears to increase the chance of finding loot and coming out successfully. On the other hand, having an insufficient amount of Athletic skill can result in the Sim being unable to make further progress after encountering an underground obstacle, forcing them to abandon the adventure prematurely. Whether or not the adventure is successful, the Sim may come up singed.

While drilling with the Miner, traveling through a tunnel to another hole, or on an underground adventure, a Sim's hygiene will drop rapidly.

Sims who use the miner at night will disturb sleeping Sims on nearby lots, unless those Sims have the Heavy Sleeper trait. Sims will leave their homes and run to the miner and the Sim who is using it, and over a prolonged period of time, will form negative relationships with the person operating the Miner. This occurs on both the home lot and public lots. Also, drilling a hole on the lot of a police station can result in helping a criminal to escape, which can lead to a reward.
