freeOK概要：In the last combat mission through the rugged mountains of Afghanistan, the jet plane of Lieutenant Kate Sinclair, a female pilot of the Royal Air Force, was shot down over one of the most dangerous rebel strongholds. When the rebels chased her at the crash site, she found a refuge in an abandoned underground bunker. After tracking Sinclair deep into the bunker, the rebels unexpectedly awakened a man-made deadly biological weapon called Ravagers - half human, half alien, eager for human food. She was frightened and watched as these creatures tore apart the man chasing her. Sinclair narrowly escaped and was sent to search for her by a US Army patrol to pick her up. Major Roy Finch, the commander of the local US military outpost "Apache Fort", and his group of brave soldiers from a ragtag group found it difficult to believe that mutated monsters were hidden in these mountains. Without knowing that she had been traced to their base, dozens of fierce creatures had already swarmed towards them.
