With the “Get To Work” expansion, players gained access to new professions, including scientist, detective, and doctor. It was within the scientist’s career that the marvel of invention, Wheatley, was unveiled. This nifty gadget allowed players to invent and upgrade multiple devices, each with its own unique and extraordinary abilities.

Momentum Conserver – The Focused Buff

One of Wheatley’s early creations was the Momentum Conserver, a device that provided Sims with a +1 Focused Buff. With this newfound focus, Sims were better equipped to excel in their daily tasks, making them more productive and efficient in their endeavours.

SimRay – A Powerful Tool of Transformation

Perhaps the most versatile invention to come out of Wheatley’s workshop was the SimRay. This multifunctional device could be upgraded to perform an array of mind-boggling tasks.

Initially, it granted Sims the ability to freeze other Sims in their tracks momentarily, but with some upgrades, it could do so much more. From transforming Sims and objects to even taking control of a subject’s mind, the SimRay was a tool of immense power and amusement.

Hover Lamp – Shedding Light on Creativity

The Hover Lamp was not only a source of illuminating light but also a quirky decoration that granted +2 Focus. Its alien-like appearance added a touch of otherworldly charm to any room, and its ability to enhance a Sim’s focus made it a valuable addition for those who sought to maximise their productivity.

Satellite Dish – Reaching for the Stars

For players who craved a taste of the extraterrestrial, Wheatley offered the Satellite Dish. This invention allowed Sims to affect the mood of entire neighbourhoods, communicate with aliens, and even tune into a special extraterrestrial TV station.

With the Satellite Dish, the Sims’ world expanded beyond the boundaries of Earth, providing them with a cosmic connection.

Cloning Machine – Doubling the Fun

The Cloning Machine was a fascinating invention that allowed Sims to duplicate collectibles, food, and even other Sims! The possibilities were endless;

Sims could now have clones of themselves to handle their daily responsibilities or experiment with replicating valuable items for personal gain. The Cloning Machine opened up new avenues of creativity and hilarity for players to explore.

Electroflux Wormhole Generator – A Journey Beyond

The crown jewel of Wheatley’s inventions was the Electroflux Wormhole Generator, a device that enabled Sims to contact aliens, test the environment of distant planets, and even travel to the mysterious and exotic Planet SixAm.

The Wormhole Generator took Sim adventurers on thrilling intergalactic journeys, allowing them to explore the unknown and experience wonders beyond their imagination.
