Half-Life Walkthrough

On A Rail

When the train stops, listen to the guard's story about where to go next, and then hop off the car and press the switch to raise the gate. Continue driving merrily along. (If you time it right, you can kill the guard when he just begins to speak and he'll continue his monologue despite the obvious problem of being dead.)

Keep driving until you see a little rail-switching sign with an arrow on it. Shoot it quick to switch the tracks so you'll continue straight instead of looping around to the right.

Stop when you come upon a platform with a bullsquid and a set of stairs. Mount the stairs but be careful of a sentry gun behind some crates. Toss a grenade to take it out. Once it's clear, throw the switch to move the big hanging hook that was impeding your progress.

Back on the train, shoot the next track-switcher to turn to the left and continue down the tunnel that was blocked before.

You'll take a trip up a spinning elevator with soldiers picking you off from all angles. Once you have this under control, continue down the railway, stopping to open a gate in you way. Eventually the tracks will end and you'll need to continue on foot.

Go down the left hallway but be careful for a big artillery gun around the next turn. Avoid it however you want, then turn right and go through the blast doors. Climb down the ladder and find another train car.

As you continue down the railway, watch out for red lasers in your path which will activate more sentry guns. Also, there are some soldier with mounted rocket launchers which can be foiled simply by ducking behind the controls of your train car.

When your train car stops again, hop off onto the platform, killing a few aliens along the way. Down a corridor you'll see a doorway to the left which is blocked by some boxes. Use your duck-jump to get over them (jump up, then hit crouch while you're in the air.) Use the switch you find to raise another gate, then get on the train car again and keep going.

As you cononue you'll come to another great firefight with some hiding soldiers and a big artillery gun. Liberal use of grenades is recommended, and the switch near the big gun will open the gate so you can continue.

Keep going, watching out for incoming rockets and big hanging boxes. Shoot the track-switcher to continue straight ahead. At the next gate, take the ladder down and keep going down the train tracks.

Keep going, killing mounted guns and soldiers all the way. You'll go through a set of doors with a nasty trap behind it (lots of things to deal with.) Enter the little complex to the right of that big slanty-floored hole in the ground.

Here's a nice puzzle. You could try to walk up the stairs, if you wanted to trip the red triplasers and blow everything to hell. Instead, push the two boxes around the side of the stairs and use them to bypass the triplasers entirely.

Go find the control room and launch that damn rocket already.

After the fireworks, go back down (be careful around the triplasers again) and through the blast doors. There will be a newly opened passageway to your left, where you'll find yet another train to ride.
