Checking on Shimane Trophy
Checking on Shimane
Use the "Check" command 200+ times.
One of the options available to you is “Check,” which brings up a magnifying glass and allows you to search the environment you're in. If something is able to be checked, the magnifying glass will turn red. Check is often used to find investigation items and further dialogue options.
This is not likely to come naturally, though by the end of all your playthroughs you should be fairly close. While playing, just check things two or three times instead of the one time needed and you'll have this unlocked in no time.
