Head left up the next staircase and into a tightly packed studio. Watch the Strider climb over a nearby rooftop and wire up a power substation leading to the Citadel. Walk down the stairs to the end, open the door (by grabbing the handle) and walk out to a terrace overlooking another part of City 17.

Grab the red bars and pull them toward you, sliding open the door and leading you into a dimly lit hallway. The yellow door on the far side of the room will unlock. Press the yellow-highlighted button on the microphone console, and watch as Eli and Russell brief you on the day’s errands. Once you’re ready to get a move on, head up the stairs and into the windowed room. You can crush those pop cans on the shelf and toss them over the ledge, or you can even tune the radio to check out what’s on the airwaves in City 17.

Take as much time as you need to get accustomed to the controls, play with the physics, and attenuate yourself to being in the shoes of Alyx Vance. The first things you’ll notice around you are some loose objects, a radio, and a lot of Combine activity. Take in the fresh air, and get ready for a grand adventure. Look out over the horizon to drink in a perfect view of the Citadel, a towering superstructure which serves as the head of operations on Earth for the oppressive Combine empire, which you may remember as a returning player from Half-Life 2 and its subsequent episodes.
