The canyon wall from the first part of the Half-Life chapter Surface Tension, which Gordon used to get to the Lambda Complex, can be seen.

The rest of the opening sequence consists of Adrian continually losing and regaining consciousness, seeing conflict between the Xen aliens and the Marines who survived the crash. As Adrian 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 Crafts, along with several other Osprey Heliplanes (the first one is codenamed Goose 3).

After his transport aircraft is taken down by an Alien Craft and he is cut off from the rest of his unit, the "clean-up" mission is abandoned and Adrian joins forces with the scattered survivors seeking escape.īefore the first chapter of Half-Life: Opposing Force, a short introduction is shown.

As the game begins, Adrian is part of the clean-up operation.
