The Sims 4 will get its first expansion, Get to Work, this April, Maxis and Electronic Arts announced today. The add-on will bring a handful of new active careers to EA's long-running life simulation, letting players explore professions in medicine, police work, science and retail.

As a doctor, your Sim can treat diseases, perform surgery and, for the first time, even deliver babies. Sims can also play police detective, solving crimes and interrogating other Sims — and based on the expansion's first trailer, send old ladies to county jail. The science career path lets players discover new inventions in The Sims 4 and use those creations for good or evil. Get to Work will also let players create a retail business — a bakery, clothing boutique, art gallery, book store — hire employees and build out their store in Build Mode.

New career venues, including a hospital, police station and science lab, will be included in the expansion to give those new career paths a home.

The Sims 4: Get to Work will also add new skills: photography and baking.

Finally, in a more wild tangent, the expansion will also introduce aliens. Players can uncover which Sims are aliens in disguise — it's unclear whether They Live-style glasses are involved — and explore a new "Alien Dimension."

The Sims 4: Get to Work will be released in April from Mac and Windows PC for $39.99. The expansion is available to pre-order from EA's Origin now.
