Outcry

Outcry is a psychological thriller in the first-person perspective and a point-and-click adventure video game. You receive a letter from your brother, a scientist, who invites you to his home, so he can show you the results of his project and give you ideas for your next book. However, when you get there, you discover that your brother has mysteriously disappeared, leaving you all his material possessions - including a large, strange machine and a message asking you not to reproduce his experiments.
