"Ambient sound effects help to relay a creepy atmosphere and the game is further enhanced by the solid music, one of the best I have personally heard in a horror game." - Hooked Gamers
"Still an excellent soundtrack that contributes heavily to the game's mood." - IGN
Penumbra: Black Plague
"Like the sound effects, the music in Penumbra: Black Plague is outstanding. The soundtrack is fittingly dark and eerie, and does a great job of ramping up the suspense in key parts of the game. The music never feels forced and never distracts you from the action, but nicely blends into the rest of the game's lugubrious atmosphere. The frequently discordant tones, heavily relying on the piano, end up being absolutely central to your sense of disorientation." - Adrenaline Vault
" ...for me the atmosphere was threaded together by the combination of perspective, soundtrack, and the physics...
...the muted cries, clanks, and hisses of the ambient tracks are excellent and contribute heavily to the game's atmosphere." - IGN
"The Good: Great music and sound effects." - GameSpot
"Distant noises immerse players into the game, while whispers and strange noises, along with music that is similarly creepy, works wonders to draw players in immediately. Even in its brevity, Black Plague stands as a testament to the ability that ambient audio can make even a lower budget game better." - Game Positive
"Try this game after midnight with all the lights turned off and 5.1 sound system plugged to your PC. See if you are a real man in this situation! A plus for the menu music..." - Games32
"The audio is truly great..." - Game Industry News
"The music is great, as are the sound effects, which really helps to drive home the fact that you're in a scary, surreal world." - Cheat Code Central
"The atmosphere is relentlessly dark and hostile, with fantastic use of audio to convince you that there's something truly horrible round the next corner." - PC Gamer UK
"With sound effects and music of such a high quality, we recommend you play with the volume turned up loud!" - Gamers Universe
Penumbra: Overture
"The music in Penumbra does an awesome job of enhancing the feel of the game, with piano the most prominent instrument but with other orchestral instruments also playing a role. For example, when an enemy is close by, the soundtrack becomes tense. When you discover the creature, the score becomes frantic as the enemy begins to rip you to shreds. When you find something horrific, a sudden, jarring chord increases the shock. Often, before a surprising encounter, there's little or no music, which makes you feel like everything is a little too quiet. The title screen music should be a tip-off, for it's an epic masterpiece." - Adrenaline Vault
"The game's audio is stellar." - GameSpot
"Immersive and suspenseful games can be made or broken by audio choices and Penumbra made all the right moves." - Gamer's Hell
"On the plus side, the game's music is a treat. It's very well produced, and dynamically changes based on the current situation." - YouGamers
"Penumbra is a pretty silent game, once the music kicks in, it matches the situation perfectly. Sometimes spooky, sometimes hectic, its fitting really good into the game." - DNC Games-Magazine
"The audio is superb and is primarily responsible (more than the graphics) for the eerie ambience of this game. Playing this game alone and in the dark, with the sounds turned up, can be truly terrifying (in a good sense)! The haunted music and ambient sound effects from a distance work well to create a sense of impending doom that is relentless throughout the game." - Adventure Classic Gaming
