The three keys
This task is very short and it will take you only a few minutes to complete it. The goal is simple - you have to find three keys and activate the mechanism that drops the body into the crusher. Each of them is located in one of the three sectors.
The whole thing looks very similar to the previous mission. On the monitor located at the entrance to a given zone, there is a TV with a clue. The symbol that is displayed on it is also on the body with the key .
Look for question marks . Thanks to them, you will easily track down the next bodies and find the keys you are looking for.
Also remember that there are several entrances to individual sectors. At each of them you will find a TV with a clue.
As soon as you collect the keys, return to the crusher and activate all three mechanisms. This will complete the quest and you will be able to call the train.
