Lock down the whole area and scan the virus. Where's the third one?

The location of the scanner in each polluted area is different. Anyway, in a word, just search every corner as quickly as possible, and don't let go of any corner. At the same time, don't leave the area. Move as fast as possible in the area and keep your eyes bright. The model of the virus scanner is still easy to recognize and there will be interactive prompts when approaching (the model will flash slightly).

Several polluted areas that need attention:

1. A large polluted area will be encountered in the middle and late stage of the task. The whole terrain is an enclosed square, and there are some tunnels on the ground in the square. There are ***5 virus scanners in this area, all of which are located in the tunnels, and the final virus data sending computer is located next to the truck near the other exit of the square.

2. This area of Turtle Bay is also the highest level area that will eventually come. There is only one polluted area, which is also the most difficult polluted area in the whole game. This is a large shopping mall, with only four scanners in total, but the location is very difficult to find. This area not only needs you to find virus scanners, but also needs you to solve puzzles in order to open some channels and place virus scanners. Don't open the first scanner at the door after entering this area. First, enter the underground control room through the stairs and elevators in and behind the mall to remove the access control on the second and third floors and the elevator leading to the roof, then go to the first floor to turn on the virus scanner, and then look for the remaining three scanners on the second and third floors one by one. After finding them, take the right elevator to the roof to start the scanner that sends virus data to complete the task.
