Maintenance in the game is greatly simplified, both because of the design, the gameplay, as well as other reasons, but the important thing is that it works. How does it work?
You repair things using the telephone and approaching the broken thing. Aim at it and select with the mouse wheel one of the servicing firms, and confirm the selection and payment with LMB. When we have a phone in our hands, we can look up any equipment and see us information about its technical condition. In turn, when we choose one of the companies, the information next to the company logo will tell us how much money the company wants for the repair and how much time it will take. Once approved, the repair will commence right away, symbolized by an icon with a wrench, along with a clock that shows how much more work is left until the end.
When the icon disappears, the repair is over.
It is important to note that you should not save money on repairs - equipment that hasn't been properly restored can get damaged much faster and, as a result, will require more money.
What if you lost your phone?
Just press once on the stand of the phone, and give it time to return to its place.
