Wivenhoe: The fall of Ravenholm is a single-player modification for Half-Life 2, designed by Travis Draper of Brisbane, Australia.
The story is a prelude to the events of Half-Life 2 and explains various events and locations from within the game itself. The player takes part in a coordinated civilian uprising to prevent the shelling of Ravenholm, the last bastion held by the civilians in City 17.
Wivenhoe is a Combine-controlled dam facility upriver from City 17; the environments consist of the spillway, dam wall, indoor facility, and a bridge across the ravine. These environments incorporate stealth, action, and horror gameplay.
