As with any modified game file, there are risks associated with using the TRNT.rar file. Since it is a third-party modification, there is a possibility that it may contain malware, viruses, or other types of malicious code.
The game's core gameplay revolves around digging, managing resources, and optimizing duplicant happiness and productivity. Players must excavate the asteroid to create habitable areas, manage gas levels, and balance the duplicants' basic needs with their psychological and emotional well-being. The game features a rich array of systems, from temperature and gas management to sanitation and duplicant relationships.
This is the million-dollar question. A file with TRNT in the name is – it comes from an anonymous uploader. So treat it like a stray USB stick: caution first.
