Final Descent (AppID: 3481510)

You are a detective working for the police. Your current mission: locate a massive, abandoned facility hidden deep within a Russian forest. According to scattered reports, the place was used for highly suspicious activities.

To reach the depths, you'll descend countless floors sometimes by rusted elevator. The facility is vast, spanning numerous levels. Each level is completely different and hides its own challenges, surprises and dangerous entities.

You don’t know what awaits in the abyss.

But you will — soon.

You are equipped with a flashlight, a photo camera and a high-tech objective-finding device known as S.E.R.A (Spectral Emission Recognition Apparatus) — capable of detecting nearby objects with fingerprints or fresh blood.

Your task: find the fragment required to continue your descent to the next floor.

Throughout your descent, you’ll need to solve puzzles, uncover new challenges. There are secrets scattered along the way. Every level may bring you closer to the truth — or further into the unknown.

If you reach the bottom you’ll know everything...

You must do this.
