I've seen the post you made on the forum called "Grimdark". I see you are in need of survival songs, and I have some that might be of assistance.

1. Batman Begins - Tadarida
2. Amnesia: The Dark Descent - Danger is Close
3. The Grey - The Morning After
4. The Grey - Running From Wolves
5. The Grey - Eyes Glowing
6. Robert Christopher - Haunted Sky
7. When Darkness Begins
8. Amnesia - Suitor Themes

I hope these tracks may be of assistance.
