Siren

On one hand I consider this game a truly underrated, innovative gem of the horror genre that deserved more attention, on the other hand I can understand why it never took off since it's a victim of its own ambition; it brings a lot of new ideas to the table, most of which work better conceptually than practically. It's very difficult to figure out what to do and where to go, and even more difficult to actually do it. Recommended for horror fans but make sure to keep a guide on hand.

By the creator of Silent Hill, it kind of improve on the horror elements and has an original way to tell its story. The main drawback is that it's often unclear of what you should do to complete an objective.
