There's a health dispenser here, as well as a few Headcrabs.

Head back in and climb through the vent into the computer room. You may want to head back out to the tram first, so hit the lock mechanism with the Crowbar. A ventilation grate will be blown off by a nearby explosion, allowing you to crawl into the computer There's also a health dispenser back by the stalls. Guthrie's locker is open, and you can get some clips for the pistol.

At this point, you can go back to the locker room.

When you get to the next floor, you'll see a guard firing at two Zombies. There's no way you can prevent the tragedy that occurs, so crawl into the shaft and climb up the ladder.

When you come to the second elevator, break the glass.

Pick up the Crowbar, break the glass on the door, and crawl through. Wait for the second laser beam to make its way to the floor, You'll come to a room with a thin red laser beam.Д¬rawl under the beam, then walk carefully toward the end of the hallway. Wait for it toДestroy the door, then time your run across the room so the beam doesn't hit you. A high-powered energy beam is shooting out of the test chamber.

Before you go rushing into the next room, be careful.

It's not going to be as easy as it sounds. He'll also tell you to get to the surface. He'll follow you over to the security door and let you out. When you find the two Scientists, talk to the one who isn't injured. Normally, you'd be denied access, but it seems the accident has caused things to malfunction. Leave the test chamber, and use the retinal scanner.

You need to start making your way back up to the exit.

So that's a resonance cascade scenario.

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

You'll be given specific instructions during the experiment.

But the administrator is adamant aboutД¬ontinuing, so once they activate the retinal scanners, go into the chamber. Seems there's a slight chance of a 'resonance cascade scenario,' whatever that is. Two more Scientists will be waiting, and they'll briefly discuss the risks involved in today'sД®xperiment. Walk to the second elevator and head down to the chamber.

When they're done explaining today's experiment, they'll activate the retinal scanners. Lab, follow the hallway until you come to a group of Scientists who are waiting for you. Press the button to open the elevator, then get in and press the button to activate the elevator. Now leave the locker room and follow the hallway around to the test lab door. Inside, you'll find some energy for the HEV suit. It's on the back wall, near the stalls, and it's labeled with your name, 'Freeman.' Before leaving the locker room, check your locker.Press the middle button on the console to open the storage pod, then walk down and put on the suit. Walk into the back, where the HEV suits are stored. Head down the hallway until you come to the locker room. The test chamber is to the left, but you need to put on the HEV suit before you'll be permitted access. Talk to the security guard at the front desk, then head down the hallway. You're running a little late, so let's try to get down to the test chamber as quickly as possible.

Follow him to the security door, and he'll let you in.

Once you arrive at your destination, wait for the security guard to open the tram door.

There are plenty of supplies in Black Mesa, but sometimes you have to search for them. 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. You never know what might come in handy later. Look around the various locales, and pay attention to the voice on the loudspeaker. You've got a long day ahead of you, and this is probably the only chance you'll get to relax.
