“Outbreak, outbreak, outbreak!”
The
“The main station’s just ahead!”
Swim up the river until you come to a large red train cart blocking your way. Hidden on the left is a ladder leading up to the roof where you can drop in on the citizen and Vortigaunt. Listen to them and get a quick energy boost before going through the door they show you. Avoid the fire and crowbar down the blocking, also being mindful of the barnacle above. You can shoot it, but it is easier (and doesn’t waste ammo) to get out the crowbar and deliberately get caught on its tongue. Swing the weapon above you when in range, resulting in an instant kill. Or simply run round it. You come upon a battle between rebels and the CPs. Don’t stay out in the open too long, as the cops have a mounted gun in place that will cut you to shreds. Make a sharp right as soon as you come into the main arena and climb into the sewers where you saw a rebel being killed by a CP. Run up the tunnel and you come up in a room filled with health and ammo. Climb the ladder to come up behind the mounted gun and dispatch the cops.
You’ll need the mounted gun as another wave of officers arrives and this is the best way to deal with them. Again plenty of explosive barrels are around so put them to good use. There is a single barrel on a ledge to your right which you have to blow up to create a bridge to continue down. You can tell when to leave when an APC zooms up the side and starts launching rockets. Run down the side path to the right of the gun forwards over the pile of rubble into another open space. Take a sharp left past a citizen crouching in a pipe. You find yourself in a series of large vertical cylindrical rooms. The first room has a couple of cops standing over head on a grate. You might dispatch one of them if you’re very quick but they’ll probably just get away. In the second room, you’ll find water on the floor. Drop down and watch the cops from earlier throw a couple of barrels down. Even if you shoot them, you can’t blow them. Wait till a burning one appears then dive under water. Stay there until the explosions have finished then surface and kill the CPs. Continue forward until you come out into a new arena. Some cops decide the best way to attack is to stand on a rickety bridge with explosive barrels under it.
Blow these up to kill them all. The next room has a floor covered in some kind of grease meaning that you keep sliding even after you stop pressing forward. This is made more difficult by the barnacles hanging on the roof. The best thing to do is to use the explosive barrel nearby. Throw it down to the slope towards the barnacles. When one of them latches onto it shoot it twice, setting it on fire. When it explodes, the blast should kill most if not all the barnacles. Travel down the slope towards a deep area of water. A large wooden board is in front of you and you’ll need that as 4 or 5 CPs can be found over head shooting down onto you. Hide behind the panel, swim down, around it and up shoot a cop or two and then back under and behind the ramp to reload and recharge. When all the CPs you can see are dead, head towards the ladder on the far wall and use the platforms as stepping stones up to the sewer entrance. More cops will probably appear and drop explosive barrels down on you. If you’re getting cut to pieces, dive under water-harder to be hit. Get round the platforms up to a tunnel into an underground room.
Meet the Helicopter
In the new area you have a seesaw as the only path forward, but the wrong end is pointing up. You need to weigh down the other. To do so, pick up the bricks scattered around the area and put them on the end of the seesaw you wish to push down. Put them as far from the middle as you can-this increases their overall force (force=mass x distance). You’ll probably need pretty much all the bricks, and they’re scattered everywhere. Eventually you will be able to climb to the top but don’t rush out blindly. A helicopter hovers down. Stay in the shadows to avoid it. This hunter-chopper will be following you for the rest of this and the next level. When it is gone make a left then a left again. The copter will be following you and shooting. Past the ruined gate, shoot the barnacle, don’t get caught by it (it leaves you in the open and defenceless) and move the barrels out of the way and get through the door. Opposite you is a ladder. Climb down it and pick up the health and ammo at the bottom. Return up, and move up the slope, turning left at the top. There is a pool of water with a low ceiling with a dead body, explosive barrel and health at the back of the room. Return back and walk to the right of the upper level. Here you see a greased slope with a collection of barnacles. Throw the explosive barrel down the slope and shoot it twice when the barnacles pick it up.
Follow it down the slope and jump over the railings to the next room, which has exactly the same setup. Repeat. Open the door and run to the left, where the helicopter can shoot at you for the first time.
“Thank god you’re not the guy they’re looking for…”
Move forward down the corridor being wary of a couple of explosive barrels, until you come up to secret depot for the railroad. Before you can carry on, the area is invaded by manhacks. Copy the citizen and use your crowbar and lay into the ‘hacks (making baseball/cricket noises optional, but encouraged). Later in the game, the gravity gun or shotgun become more useful. With the robots fought off look to the left of the door you came through and climb the ladder, searching the two overhead areas for both health and ammo. Move down the corridor the manhacks came from to find a door with manhacks the other side. You can either shoot them or open come to a pool of water with a large rotating wheel in the middle. Jump in and swim through the door underwater on the left. There is an air hole half way along. You come out near a large pipe. Follow it round past the scanner that flies at you around to the left where three more CPs are waiting, along with manhacks. Kill them all and go back up the stairs with the barnacle over them and jump on the pipe. Go back the way you came, towards the jets of steam, avoiding these and the barnacles (getting caught on the tongue immobilises you in the steam). When you can go no further look on the right hand wall for a lambda logo near some rotten looking planks on the wall and destroy these and drop down into the gap with another small swimming space. Swimming through here brings you out just in front of a combine ambush, where two cops man an explosive-barrel-filled trailer. If the barrels are too close jump back into the water to escape from most of the damage. There are three more CPs around the corner and a swarm of manhacks the other side of the door. With these dispatched, destroy the air vent cover and crawl inside. Move down this until it seems you can go no further then destroy the floor. You drop into a room with explosive barrels and manhacks. Move near the ladder and shoot one of the barrels twice. Drop down the ladder into the water below and wait for the explosions to end. Remain in the water to kill the rest of the manhacks as they move slower in liquids. Climb to the top of the ladder and jump to the central pipe and across to the opposite side. In the next room you have to reach the red turn valve half way down by jumping from pipe to pipe.
From the location on the screenshot, fall down to the two large orange pipes then the bright white double pipe. From here you can jump to the valve, turning it to release the water. Return to the room where you fought the manhacks, go down the ladder and through the now accessible drain. At the bottom of the next room area series of boxes and wooden wheels trapped at the floor with planks. Use the crowbar to destroy the planks and let them float to the surface. Use “use” to reposition them and make a bridge.
Your ride, sir...
In the final underground room, you are assaulted by more CPs and manhacks. Move towards them, climbing the ladder on the ledge to the left. A side room has some health and ammo hidden behind some barrels and barnacles. In the main room climb the ladder and walk all the way along the makeshift walkway until you reach the lambda logo when you can drop down. Move out into the open avoiding the liquid which is poisonous. Move towards the rebel, looking out for the crate of SMG ammo that never runs out. Go towards where the headcrabs came from and watch as shells come down. Each headcrab rocket has 3 crabs in them so there will be that many in the vicinity. Carry on round killing the crabs as you go. Any zombies you see lying down my not be dead but simply resting. They also have the habit of rising up from toxic sludge.
When you reach the electrified shipping crate, lure the headcrabs in and wait for them to touch the walls. Eventually you reach an open area. Turn left and follow the wooden walkway to reach the airboat dock.
Climb in the vehicle and travel down the river following the bend. The gate can be cleared by stopping the airboat to the right. Move round to the pile of boxes being aware of the headcrab lurking behind them. You must turn the crank until it stops to lock it in place. Climb back in the boat, and continue on to Water Hazard.
