Ground Zero

You fling open the trap door and quickly climb down; you figure as soon as they attempt to come in after you, you can easily pick them off.

Unfortunately the Combine soldiers are a little too smart for that. They've been fighting cyborgs for so long that their usual response to a tricky situation is throw explosives at it. Which is exactly what they do.

They dump a few more grenades down the hatch, you see them and get cover just in time, but the explosion causes a weakening of the foundation and ultimately causing part of the store to collapse in on itself. Your murderous ways are finally put to an end when a wooden beam falls on your head and the rest of the debris buries your unconscious body forever.
