Alien Lockdown (2004) on Netflix

Plot summary

Dr. Alan Woodman runs experiments in a secret government laboratory inside a top-secret military base. He is trying to turn a violent alien life form into a weapon, and the trial fails. The creature breaks loose, kills the staff in its path, and leaves Woodman and his assistant Charlie as the only survivors. The two seal the facility and send a distress call. A covert military force responds, led by Commander Rita Talon, with orders to find and destroy the creature. Talon's soldiers team up with Woodman and Charlie and begin to search the compound. The alien had lain dormant for centuries before the experiments began.
