The Ravenholm Gauntlet — Half-Life 2 Walkthrough

You'll find yourself in the dark, dilapidated streets of Ravenholm, overrun by various types of Zombies and Headcrabs. Ammo is extremely scarce here, forcing you to rely heavily on the Gravity Gun and environmental traps. Look for sawblades, explosive barrels, and other heavy objects to launch at enemies. Father Grigori, a deranged priest, will occasionally assist you by sniping zombies or providing hints. Use the environment to your advantage: set up traps, climb to higher ground, and conserve your precious bullets. The atmosphere is oppressive and terrifying, so stay alert.
