The chapter is known as The Office Warrens in this version. The player has to push objects, explore air ducts, activate or deactivate various electrical mechanisms, and avoid hazards to proceed in the chapter. Most of the puzzles involve the player trying to reach the other side of locked doors, which forces them to find alternate paths to reach their goal. They can help him kill the enemies, or heal him when he is low on health. The player is able to interact with these non-player human characters.

There are several civilians who barricaded themselves in their rooms, hiding from the rampant aliens overrunning the facility. Along the way, the player overhears rumors that the military has arrived to rescue the people.

The goal is to go through ruined alien-infested complex to reach the surface level.

The elevator from the previous chapter takes the player to the Administration Center in Sector D, which consists of offices, storage rooms, and a cafeteria with a large walk-in freezer. For the the game's full story, see the Half-Life storyline article.
