Gordon Freeman is back! Along with scientist Eli Vance and his daughter Alyx, your mission is to save the world from total alien domination. See, that little incident in Black Mesa was just the beginning: now those pesky Xen invaders and a new threat called the Combine have spread across the whole Earth, causing massive amounts of death and destruction. It’s up to you to set things right.
