Was "The Descent" based on a factual concept?

I am bored and wanna research something. There is The Descent and one other movie I remember. Can't recall the name though. Something to do with a facility in the side of a mountain and there was a vault and when it was opened there was creatures similar to the ones on The Descent that came out but these ones were on steroids compared to the ones on descent.

Is stuff like this based on factual creatures?
