Fic Rec for Fallback Friday! The Last Level by thegraytigress

[http://archiveofourown.org/works/1972494]

From the author's summary: There are dark places in the world. A battle with an old enemy lands Tony, Steve, and Clint in a hellish nightmare and only their faith in each other stands between them and death.

This is one of the first stories I read by thegraytigress. The trio of Tony, Steve, and Clint trapped in a old missile silo (it was written and published ages before CA:CW). What I like about this story is that each character gets to shine but at the same time you get the wonderful heroics of Steve Rogers for his team mates. I highly recommend you read this story and all of the rest of thegraytigress' work!

And it is Gen so no pairings!
