The Shadow Walkers

When a group of scientists and soldiers awaken in an underground laboratory with their memories wiped clean, they must struggle to find an escape route while being pursued by a terrifying horde of genetic abominations in director Mark Steven Grove's breathless action horror yarn. Though they first seemed like innocent pawns in a sadistic game of man versus mutation, these desperate souls gradually discover just how relative innocence can be as their memories slowly come into focus. Now, of they can only escape the ripping talons and razor sharp teeth of an unknown enemy, they may just be able to find out exactly who, or what, set their mysterious ordeal into motion. ~ Jason Buchanan, All Movie Guide
