The Sims 4 has finally introduced a burglar character with its latest free update, bringing back the classic burglary gameplay that was absent from previous iterations of the game. The new addition, Robin Banks, is called to your home by her theme song and will search for valuable items to steal.
To thwart her plans, players can call the police, engage in a fist fight, or upgrade the burglar alarm. Upgrading the alarm allows Sims to automatically call the police, reducing the frequency of break-ins, or even zap the burglar upon detection.
The update is free and compatible with base game only, but it will interact with expansion packs like Pets, which adds a new dynamic where dogs chase away robbers. Players can also choose from 37 interactions and receive up to 50 unique reactions from notable characters in their households.
