Observing the path ahead image - Quarantine Zone mod for Half-Life 2: Episode Two

Set in a seemingly abandoned facility, located in the mountain area far off a remote mining village, the player gradually unveils the origin of the facility. Isolated with no company except the obscure voices erupting from an old portable radio receiver, the player strives to escape the facilty. But since the facility's environment is unfamiliar, yet you don't possess the proficiency needed to overcome and manage the different obstacles and possible threats that clog up its endless tunnels. The path ahead is long and hostile.
