This time I will show you where the multi-purpose shotgun suppressor is in Seven Days World. In fact, many people don't know how to solve it, so the editor will give you detailed steps to solve this problem, so that you can solve this problem in one go.
First of all, you have to unlock the second stage of the season event and open all the maps.
Next, go to the Lone Wolf Wasteland and look for the place on the upper right side of the Institute of Life Evolution, which is marked on the map.
Once there, you'll see something that looks like a camera, so check it out.
After checking, you imitate the rejection action made by the projection. At this time, the treasure box will come out. Open the treasure box, and the shotgun suppressor is waiting for you inside.
