Opposing Force: Incoming

The Replay Experience Experiment: Half-Life: Opposing Force incoming

As the game begins, Shephard is part of the clean-up operation. After his transport aircraft is taken down by an Alien Aircraft and he is cut off from the rest of his unit, the “clean-up” mission is abandoned and Shephard joins forces with the scattered survivors seeking escape.

Before the first chapter of Half-Life: Opposing Force, a short introduction is shown.

As Adrian Shephard and his fellow HECU comrades are approaching the LZ (Landing Zone 117) at the Black Mesa Research Facility, his plane (codenamed Goose 7) is shot down by alien aircraft, along with several other V-22 Ospreys (the first one is codenamed Goose 3).

The rest of the opening sequence consists of Shephard continually losing and regaining consciousness, seeing conflict between the Xen aliens and the Marines who survived the crash.

The Half-Life: Opposing Force soundtrack was composed by Chris Jensen. It was reused for the Half-Life: Blue Shift soundtrack. The Half-Life soundtrack by Kelly Bailey replaces the original one in the Steam releases of Opposing Force and Blue Shift.

However, it’s easy to get the original back. Below is a file that contains all the music, along with isntructions of how to use it.

Here is part of the text from the readme_opfor.txt.

In this chapter, the HECU determine that they’re fighting a losing battle against the Xen aliens and, having continually failed to neutralize Freeman, abandon their mission and begin to evacuate the facility, calling in air strikes and heavy artillery to cover their retreat. Meanwhile, Gordon makes his way into an underground storage garage to avoid the bombardments, and eventually fights his way through scores of aliens and several groups of the decimated HECU forces before reaching the Lambda Complex.
The Marines begin to evacuate Black Mesa and air strikes begin. Gordon navigates underground water channels and tries to avoid scores of alien invaders as they pick off remaining Marine stragglers.
