The "Sims 4 Get to Work" expansion pack has been available this week, with three new playable careers -- and aliens.

Kotaku reported that YouTube channel Somewhat Awesome Games posted a guide on how players can get the alien stuff in the "Sims 4: Get to Work."

Based on the video, the players on the "Sims 4" need to reach the level nine in the Science career path and invent the Electroflux Wormhole Generator device. Then, they must install the wormhole generator on a spaceship, which is either the one located at the new research facility the expansion pack adds in the game or the one that the players already own and have installed at the scientist Sim's home.

Lastly, select the Travel Through Wormhole from the options available when clicking the Upgrade Spaceship. After the loading screen, the player will be able to get down on the alien planet and start to socialize with aliens.

The Sims 4 News reported that in the "Sims 4: Get to Work" aliens can wear their work uniforms when they are working whether they are in disguise or not. If an alien is in disguise, they can gain access to the clothes that the normal Sims wear.

It was previously reported that aliens can impregnate female and male Sims by woohoo, and based on SimGuru Q&A, if a female alien woohoo's with a human male, there is a chance that both of them may become pregnant.

The site added that alien abductions have a higher chance of occurring from socializing with aliens, or being a scientist and having science-related objects such as a rocket or the home lot of the Sims.

In addition, the option to take a selfie is located on the phone in the entertainment menu, Sims can take a selfie with another Sim by clicking the Take Photo With on the camera or phone.
