Dust mod for Half-Life 2

The planet of Ahria is composed entirely of desert. Through divine will or sheer luck the people have thrived on the plateau-cities of Refuge and Endeavor. Both plateaus contain massive aquifers of water that have lasted for nearly seven thousand years. The theocratic government has kept peace for centuries, massive and daring mining expeditions have unearthed rich mineral deposits in the Explored Traverse(1700 sq. mi of mapped terrain), and the use of massive aqueducts have made it possible for citizens of Refuge and Endeavor to venture beyond the cliffs of the plateaus and deeper into the Traverse. However, dangers still exist. In the three zones that surround the cities; The Cusp, The Flatlands, and The Badlands - vile beasts still stalk the dunes. Even in light of technological advances in weaponry, increasing study of arcane magicks, and the creation of the Ahrian Defense Corps - nothing will prepare the people of the dusty planet for what would happen on Day 3 of Half-Moon 6844.
