Half-Life 2 Wiki Guide



Once on the other side of the gate, Alyx will look for an alternate route across a gap in the road but become side tracked by an attack. Head down into the pit and pick up the crates to the left and in the back of a truck before proceeding down a hall. At the end of the hall there is a hole and a gate. Use the gravity gun to remove the metal bar which locks the gate shut and proceed into a grassy alley. Manhacks will come from the left so have the gravity gun ready to blast them into a wall. Then, on the right, remove the barrels from under a platform to create a ramp up to some pipes. Follow the pipes to a vent shaft and continue on.Hop down to the ground and some manhacks will come from the left. At the end of this hall there is health and energy. Return to the grassy area and notice the raised platform containing cardboard boxes. There is a supply crate hidden amongst them, so suck it down with the gravity gun. Take a right into a large vertical room with catwalks lining the outside. There will be combine soldiers firing from above onto a zombie below. Let them kill it, then shoot them from the cover of the catwalk. There is also a supply crate on their level which can be sucked down with the gravity gun.

Travel down the broken steps to the lowest level of catwalks and ready the SMG for two combine soldiers who come around the corner. There is a lambda symbol below the last level of catwalk which points out crates containing energy and health. Use the gravity gun to obtain the supplies without risking the drop to that ledge. Go down the hall where the troops entered and go into a small room on the right while blasting a poison crab. Get the supplies from the corpse, and use the gravity gun to open the locked double door ahead. Go though this door and cap the Combine soldier ahead. Look down the hall over the balcony to the left to witness combine fighting against zombies and crabs.Go around the right side of this window and watch as barnacles suck up another soldier and head crabs. Feed the barnacles some bait and walk around to the right and up some steps to find another dead body and a supply drop. Return to the watery canal and this time drop down into it. There is a small hallway that leads to a ramp leading down. Look out for a poison zombie and the headcrabs it dispenses, and check the right side of a divided concrete hall for a lambda and a small cubby hole. This hole contains rare ammo and grenades. Use the gravity gun to empty it. Follow the hall to a series of pipes that leads to another lambda symbol and some more supply crates.

Return to the area before the ramp to find a ladder. Climb up and ready the shotgun for two poison crabs at the top. Walk down the hall to the left and kill another poison crab guarding some crates. There is some health before you enter the basement of a large warehouse. Climb up the ramps until you reach the platform on the far side. Look across a catwalk to notice a red metal room. As you walk across the bridge, a grenade detonates which lights some barrels and brings the structure down. Prepare to back up from the explosion and then run on the inclined surface to the right and across the gap. There is a barnacle waiting at the end of the path so ready a gun to shoot it as you jump over the fence.In the red shack there are bolts for the crossbow. First, shoot the red barrel across the chasm and on the next level. This may take out some of the troops firing down at you. Then, hit the switch in the shack to bring down a platform, zoom in with the crossbow, and take out the soldiers on the far side. When the platform reaches the shack, hit the switch again and hop on for the ride. More soldiers will fire at you from above as you approach the next level.

Run towards the large white silos to the left and as you climb the ladder, two Combine Elite will drop through the roof. Hit them with the magnum and walk to the middle of the white pipes. From here you can see a lambda symbol to the left of the red container. The gravity gun can be used to pull the supply crate down from this area. In the middle of the white pipes there is a small metal beam which can be walked across to the other end of the warehouse. A combine soldier will attack from the red shack below.Duck under the catwalk and the hop up onto it. Look out for another Elite up above. Walk along the platform to another ladder, take it to the top level and turn around for two more elites. Then, grab the supplies and climb down one level to a supply crate. Two soldiers will fire at you from across the warehouse. Kill them and cross over to that side. Get the supplies on either side of the large red structure if you haven't yet, then disarm the hopper mine lying where the troops were standing. Drop down to that level and proceed through the door.

As you exit the warehouse, a resistance fighter exclaims that Barney is held down by sniper fire. Take a right on the street to find some supplies before they are crushed by a Combine wall. Look for the blue laser that signals where the sniper is aiming. Strafe from one side of the street to the other to stay out of his line of fire. On your third strafe, there is a pile of grenades that will prove valuable later. At the intersection where there is a blue truck, find cover from both streets, as another sniper lay in wait to the right. Dash ahead under the window and lob a grenade into it, then grab the supplies underneath.Return to the street that branched off to the right. Using the same strafing technique, enter the storefront window to find some resistance fighters. Weave across the street to an open door. In this building there are some headcrabs and a zombie. Take the ramp downstairs to find a watery area and a wounded man. He warns that the area is infested just as zombies pop up from the ground. Mow them down with the shotgun and prepare for the two fast moving zombies who come from the area in front of the stairwell. Take the stairs up to the second floor to see some zombies hit by a combine sniper. Throw a grenade across the way to take him out and then move forward to see Barney on the roof. He is being held down by another sniper, so take a trip to the infinite grenade container.

There is a sniper behind Barney, and one to the left of window the zombies where being tagged from. After clearing these windows, Barney will come down to the street and open the Combine gate. Look out for the hoppers in front of it. In the following hall, look out for two "head humpers". When entering the outdoor area, have a grenade ready to throw on top of the steps. This will clear an auto turret and two soldiers who come through the door. Head into the building and Barney will begin to describe where the center of Combine activities is located. Peer out the window to see the center of the action as Combine troops swarm from the building. Barney opens a door and as you enter the next room a blast rocks the windows to the right.Run down the steps as Barney screams about "forgetting stealth". At the exit to the building, the ground will glow white before a blast comes down from the sky. Take a right and sprint to the overturned dumpster containing health. Run around the dumpster continuing towards the building and a door. Behind the door there are two combine soldiers and a health station.

From the next door you can see a bunker straight ahead. Run to the bunker while killing the soldier who waits inside. There are some supplies in this midway point and a view of the next door straight ahead. Burst into this door with weapons ready to take out the troops who wait inside. Kill them and fill up on ammo at the gun rack and item stashes.The next door leads to the front of the building where doors will burst open and Combine Elites will run through. The energy blasts from above have stopped but the Elites are tough enemies so some SMG shells can be used to dispatch them immediately. Run to the right side of the building where there is a plug behind an energy wall and a health station. Remove the plug with the gravity gun and head up the steps to the interior.

Head to the left and go through the double doors. There is an ammo supply room immediately to the right containing an infinite grenade box. The vent ahead of the laser trip wires is a ground turret. Activate it by walking through the lasers, and then toss a grenade into the opening that appears. Be quick, or the ground turret will open fire and make short work of you and your allies. Barney opens the door to the next area which is filled with shields. Walk ahead to the exit sign but first stock up on grenades. Combine will appear at the end of the hall behind the shield. A grenade takes care of them. Turn to the right and deal with the two ground turrets in the next room. You may want to grenade the first one, then back out of the room, send the team away and get close to the second one before letting the team hit the sensor. When the second one is destroyed, two Combine soldiers will rush the room.Walk up the steps and straight across the hall at the top. Here, there are some humans trapped behind a gate and Barney sets them free. Grab the supplies in the room and help yourself to any medics that are still on the team. There are two more ground turrets outside of this room guarding the first of three generators. Keep the team back and drop a grenade into the holes to get rid of this menace. Enter the central room and blast the generator with the gravity gun. Facing the generator, head to the right down a hall that will take you to a large open room with holes in the wall.

The doors will slam shut and Combine will appear outside, firing in through the holes. Get the hoppers in the middle and activate them just outside of the steal doors. When the troops rush in they will be met with a nasty surprise. Be sure to grab the supply crates on top of the bookshelf and enter the next hall where there are two more ground turrets. The strategy involving these turrets is simple. Send the team back into the previous room and dash across the lasers with Barney, but stay behind the walls before reaching the turrets. Then, approach the vents in the floor and your team will set off the sensors giving you a much better attack position.Enter the next room, stock up on supplies and destroy the next generator. Return to the center of the building and this time run to the left. Ignore the turret sensors for now and instead take the hallway to the right to find a room filled with red laser trip wires. There is a ledge leading over the lasers on the left. Then, hop onto the piece of metal next to the picture on the wall and jump into the center of the triangle of lasers. There is then room on the circular piece of metal to hop up onto the second circle and walk around it. Make sure to reset the hopper mines on the other side. Duck under the next laser and make a right. Inch onto the ledge across from the sloped pipe and then jump to this pipe to reach the other side. Pick up the pulse rifle grenades and shut down the security system.

To the right of this room is the third generator so take it out. Pick up the ammo in this room and Barney says to head for the roof. Walk back to the beginning of the room that was filled with lasers to pick up the rest of the allies and help them take care of two Combine soldiers. Remember the two ground turrets you skipped? These have been shut down and you are free to grab the crates near them. As you walk towards the center of the building a group of Combine soldiers and elites enter into the area. Chuck grenades down from the balcony to thin out their numbers, then snipe the rest of them from the top of the steps.The hall marked with the exit sign is now open and contains a health and energy station. Look out for the remaining hoppers in the area. Barney opens the door to the roof and stays to man the controls. Pick up the RPG and walk up into the stairwell. Two Combine soldiers and an auto turret await so switch from the gravity gun to the pulse rifle to beat them into submission. Your next stop is the rooftop and a city ravaged by striders.
