Ravenholm

A portion of Ravenholm, with several zombies in sight

Ravenholm is a fictional Eastern European themed town (the actual geographic location is never revealed) in the 2004 computer game Half-Life 2. It was a former mining community inhabited by escapees from the Combine-controlled City 17. Due to bombardment with Combine artillery containing Headcrabs, however, Ravenholm is now swarming with several varieties of Headcrabs and the zombie-like creatures created when they take over humans. Gordon Freeman, the game's main character, must travel through Ravenholm when the Combine attack nearby Resistance base Black Mesa East, during the chapter called "'We don't go to Ravenholm ...'". The level has also been given the nickname "Resident Half-Life", a pun on the Resident Evil series due to the mass amount of zombies.

While fighting off hordes of zombies, Gordon meets the lone human occupant of Ravenholm, Father Grigori. The priest-turned-zombie-hunter provides assistance and advice, eventually showing Gordon the way out of the town through a mine shaft. In the final sequence, Father Grigori and Gordon must coordinate their efforts to dispatch dozens of zombies in order to ensure that Gordon makes it safely to the mine entrance.

Many areas of Ravenholm are littered with large sawblades, propane cylinders, barrels of flammable material, and booby traps that have been contrived by Father Grigori; due to the severe scarcity of ammunition in the area, Gordon must rely on the traps and the gravity gun (with which he can fling the blades and other objects) to destroy the zombies.
