The correct way to complete the finals chief detective mission is to use sonar grenades. In the game, you can successfully complete the mission by using sonar grenades to reveal the locations of 50 enemies. Please note that mission objectives cannot be achieved by relying solely on reconnaissance skills.
1. The mission clearly requires us to find 50 enemies, but it does not specify that this must be achieved through grenades or skills.
2. According to the practice of many players, it seems that this task cannot be completed by relying on skills, especially the skills of the scout character.
3. Therefore, we can reasonably infer that completing the mission may be limited to the use of items such as sonar grenades. Of course, if the skills of certain characters in the game can also achieve the goal, that would naturally be the most ideal situation.
4. Usually, when the game does not clearly indicate the specific means of completing the investigation mission, the default is to use items. If a task can be completed with a skill, this will usually be made clear in the task description.
