For Amnesia Justine it would be the dungeons where you encounter Malo De Vigny, because it was a throwback to the sewers and filled with tension and suspense like the sewers. The choir was extremely eerie, the prisons were a tension filled labyrinth and the sewers were also filled with tension and suspense. For Amnesia The Dark Descent it would be the Choir, The Sewers or The Prison.
