Single player mod to Half-Life 2. Operation happen on military base CP, where Gordon Freeman was makes runaway. To officers there was a decree from Dr. Breen - to kill Freeman. Whether it will be possible Gordon to break through persistent Civil Protection and to pass all obstacles in a way to freedom? It depends on you!
not really a trailer, more like game play video.
Also rename it: guys who come through doors >.<
agree
those guards never layed a finger or a bullet on you. this seems like a murderous rampage.
