I guess this movie was on HBO, I just watched a few scenes and then had to leave for something. Now I can't find its name. Here are some description:

It looked like there were some soldiers in a large cave complex and they were being attacked by some sub-human beings who seemed to have no legs at all. It looked as if these sub-humans had black slimy blood.

Its not Hills Have Eyes. Help!

Is it Pitch Black with Vin Diesel?

Is it Pitch Black with Vin Diesel?

No, it the earth, in present time. Actually, I also remember that probably two women escaped from the tunnel, in the end, sat in an SUV and drove to safety.

My bad... I meant it was Earth in present time.

Maybe you are looking for the Decent.

Bulls Eye! Thanks a lot mate! Cheers :-)

Glad to help!
