Hello, Mr. Freeman. Just sit back and enjoy the tram ride. You've got a long day ahead of you, and this is probably the only chance you'll get to relax. Look around the various locales, and pay attention to the voice on the loudspeaker. You never know what might come in handy later. I'm here to help you through your day. It's going to be rough. I'll assume you're planning a normally difficult workday, and also that you'll do some things on your own, such as search boxes in the workplace. There are plenty of supplies in Black Mesa, but sometimes you have to search for them.

Once you arrive at your destination, wait for the security guard to open the tram door. Follow him to the security door, and he'll let you in.

	Good morning, Mr. Freeman.

Anomalous Materials

You're running a little late, so let's try to get down to the test chamber as quickly as possible. Talk to the security guard at the front desk, then head down the hallway. Take the first right turn. At the first intersection, go right. The test chamber is to the left, but you need to put on the HEV suit before you'll be permitted access. Head down the hallway until you come to the locker room. Walk into the back, where the HEV suits are stored. Press the middle button on the console to open the storage pod, then walk down and put on the suit.

Before leaving the locker room, check your locker. It's on the back wall, near the stalls, and it's labeled with your name, "Freeman." Inside, you'll find some energy for the HEV suit. Now leave the locker room and follow the hallway around to the test lab door. The security guard will open the door. Press the button to open the elevator, then get in and press the button to activate the elevator. Once you're in the lab, follow the hallway until you come to a group of Scientists who are waiting for you.

Talk to the Scientists. When they're done explaining today's experiment, they'll activate the retinal scanners. Walk to the second elevator and head down to the chamber. Two more Scientists will be waiting, and they'll briefly discuss the risks involved in today's experiment. Seems there's a slight chance of a "resonance cascade scenario," whatever that is. But the administrator is adamant about continuing, so once they activate the retinal scanners, go into the chamber.

	Another day, another resonance cascade scenario.

You'll be given specific instructions during the experiment. Climb up the ladder to the computer console, and then press the red button when prompted. Climb down the ladder and walk over to the metal cage on the floor. This is where the sample will appear when it's ready. When the sample appears, push the cart into the beam.

So that's a resonance cascade scenario. Not good.
