Junkyard Truck is an open-world sandbox with a first-person perspective in which you take on the role of a car mechanic. In the game you have to repair an old pickup truck, replacing non-working parts with new ones. Once the car is ready to drive, you can use it to explore the open world and complete tasks (for which they give you money to buy various items). Gradually, the car can be upgraded, improving its technical characteristics. The game also has a day and night system, and the character must eat and sleep.
