They Hunger

They Hunger is a single player horror-based mod of Valve's first-person shooter Half-Life. It was released by Neil Manke's Black Widow Games in three episodes, They Hunger (2000), They Hunger 2: Rest in Pieces (2000), and They Hunger 3: Rude Awakening (2001). All three episodes were sponsored by PC Gamer and appeared on the magazine's cover disk. A fourth game made for the Source engine, They Hunger: Lost Souls, was cancelled.
