Once you've killed all the soldiers, take note of the box marked '.50 CAL MOUNTED MACHINE GUN'. Use grenades and satchels, and take cover when possible. You'll emerge in a large frieght yard, and find yourself in the middle of yet another big fight with the military. You'll encounter some more soldiers - dispose of them and continue to the freight yard. You can now exit the warehouse loading area through the door on the right. Apparently the military has orders to kill everyone and everything. If you want, backtrack to Parcel Recieving room after killing everything, and you'll be greeted with a scene of many slain scientists. The container on the left is a frozen storage container for more aliens - unfortunately, not all of them remain frozen, so, errr, don't bother opening that container. Kill everyone, and then open up the container on the right, which holds a scientist (not Rosenberg, though). (Do NOT go into Parcel Receiving area, as the soldiers will box you in and use grenades.) You'll eventually reach a large indoor loading area, where you'll find yet another squad of soldiers. Don't forget the shotgun shells on the desk. Shoot the lock on the gate, and grab all the ammo you can find. Continue until you reach the WAREHOUSE SECURITY room. Once through the window, go left (the door to the right is the second story entrance to the stairwell). A soldier will appear in a second story window and start shooting - kill him, and then climb up the crates and tires to reach the window ledge.Д¬limb through the window into the office. The door at the end of the yard will not open, so head back towards the dumpster near the yard entrance. A satchel or two should dispose of most of them - use grenades and your M4 to finish off the rest. Continue until you emerge outside.where you'll find a large squad of soldiers ready to attack. Right now, you can only exit the stairwell via the first floor, but if you go all the way up, you'll find three more soldiers to kill - and more ammo to take.Д®xit the stairwell via the first floor door. Kill him, move up the corridor, and into a stairwell. Fortunately, they don't seem to be looking for you, so continue your search and try to surprise soldiers whenever possible.ДЄs you leave the scientist, another soldier bursts in. The military has been called in, and they're seemingly everywhere in huge numbers. Rosenberg, you'll go through many of the Black Mesa freight yards, as well as many other outdoor areas. Rosenberg - and this is your next big task.ДЄs you begin your search for Dr. To do this, you'll need to find a scientist named Dr. Inside the office, talk to the dying scientist, who explains that some of the staff had a plan to try and use some of the prototype labs to escape. Kill the soldiers and grab the M4 assault carbines they drop. As you get upstairs, you'll run into some military. Grab his helmet and head upstairs.Д«e ready for a fight. Go down to start, where you'll find another dead security guard. When you leave the vent (and the immediate storage area), you'll have a choice of going upstairs or downstairs. Use your crowbar to beat up any headcrabs you encounter, and also to smash a grate leading to the second section of vents. Turn on your flashlight and make your way through. Use the crates in the corner to climb into the into the collapsed vent. You'll find your way is blocked by a pile of debris.

Use the valve to open the first passageway. Just keep moving onward, using grenades to take out bullsquids that tend to lurk around corners. The grate will open - climb down, and just before you reach the bottom, the ladder will break, dropping you into the tunnels. It hasn't been a very good day for Black Mesa personnel.ДЄs you reach the end of the passage, a bunch of military will start shooting at you, and close the door before you can get out - trapping you inside.Д«acktrack to the room in front of the SUV, open the gate, and turn the valve marked STEAM TUNNEL ACCESS. In the middle, you'll find an SUV with yet another dead security guard.

Use the keypad to open it, and head through the large tunnel. Leave the truck and walk all the way around to the other side of the surface area, where you'll find a large door. Go slow, take out the turrets, then grab the loot. To the left is a truck containing all sorts of weapons and ammo - but there are two turrets in front of it. You'll soon reach a long ladder leading to the surface.
