- Were you looking for the walkthrough of the game?
Gems are hidden items that are scattered throughout the game. Some are held by Test Subjects, while others are hidden in other locations. Collecting them all unlocks certain things, depending on the version of the game you're playing. In all versions, a special cutscene will play after the credits. In the 2.03 version, as well as the 2020 remake, you will unlock IF Mode, which stars Robin.
