Half-Life: Blue Shift

Description

The Academy never prepared you for this...

It seemed like just another day on the job... until fierce alien life forms came crashing through the walls and a military death squad invaded the hallways of Black Mesa. As security in this top-secret government facility, you must scramble to keep the scientists and yourself alive, as you extinguish the many hostiles attempting to take you out. It's going to be quite a day...
