|description=10. Collect the suspended crate.

|progress=10

Once they're dead, head up the side of the steps still intact and traverse the planks at the top of the barn. Be careful at the end, as a headcrab will drop out of the ladder and attack you. Head up the ladder and use the crowbar to dislodge the barrel blocking the wheel, and a group of supplies will plummet into the water for you to collect; some pistol and SMG ammo, and a medpack. Head back down to get them, then get back on your boat.

|description=11. Go through the open drainage pipe.

|total=45}}

Break the wooden barrier by driving through it. As you turn the corner, Combine dropships will fly overhead — they're going to drop CP units up ahead to try and stop you from getting any further. Weave in-between the various piles of dirt and debris (the Combine obviously don't think much to keeping their canals and rivers in good shape) and when you get to the dropped-in metrocops just run them over with the airboat to kill them (you need to be travelling fairly fast though). You may also notice another lambda symbol on the right by another open drainage tunnel; pull a barrel up to jump on, and climb up. Follow the tunnel along (you have to go underwater along the way) and at the end is a small cavern with some supply boxes and a zombie for you to deal with. Head back out and get back on your airboat. Head around the sharp corner in the canal and make sure to plough into the metrocops as they rope down from the canal's bank on the right. Get up some speed again, turn the right-hand corner, and use the tall wooden ramp on the left to jump across the pit and smash through some wooden supports holding up a load of junk on a wooden ledge above the polluted canal.

|description=12. Collect the supplies from the tunnels under the second APC.

|total=45}}

Carry on along the river. You will have to stay moving now, as there are a lot of things shooting at you from here on; there is a CP on the bridge which you can't kill without getting out so just ignore him and drive off the edge of the ground underneath. You will see an APC firing rockets at you on the far bank; just ignore it and keep moving to avoid its rockets. Follow the canal along and run over any CPs who decide to rope down in front of you. After the various bridges there will be another APC at the top of some large drains; ignore this too and swerve to dodge its rockets as they come towards you. As you approach the debris up ahead you'll notice that some fire starts to spread along it; quickly align yourself to use the dirt ramp to the right to leap over the wreckage and go through the tunnel under the bridge. Yet another APC will be waiting for you around the corner, and will be blowing cars and all sorts towards you. Dodge it and just make a dash for the tunnel beneath them. Once you're in there, just follow the river to the next loading screen.

|description=13. Remove the concrete blocks from the counterweight basket.

|total=45}}

Up ahead, head to the right to get around the pillars and the wreckages and you'll find another lambda symbol — some more supplies. They're held in the cage just above the symbol, but out of reach. Opposite this cage, in the shade of the pillar behind you, is another cage with two cinder blocks in it. These are winched together, so if you take the two cinder blocks out of the lower cage, it will rise and the cage with the supplies will fall for you to collect. Once you've got them, hop back in your airboat and carry on along the canal. Around the next bend, past all of the dirt piles and through the next bridge tunnel you'll be outside again, approaching another large, but this time open, gate. Unfortunately, an alarm will go off as you get near it and it will close. Great.

Once you're in your boat, drive back around the building to the gate you just opened and head on through. Sadly, only a little ways past it another helicopter will fly overhead — yet more harassment. This one will fly in front of you and drop mines to try and blow you up — and it hurts pretty badly if you drive into one by accident. Use the bank of the polluted river in the bridge section to get over the wall, and once the helicopter realizes you've survived its mine bombardment it will try to shoot at you as you get away. Go left and head into the pipe up ahead and round the corner to get away from the helicopter temporarily, and get a loading screen. After it's done, you'll be back outside, and the helicopter will be back to harass you more. Head left, and you'll get some cool chase music to accompany your dash along the river whilst dodging the helicopter's mines. If at any point you can't see the helicopter, the ring-waves its blades make on the water should be able to tell you where it is above you and can help you predict where its next mine is going to drop. When you reach the large pipes, head into them to get another brief respite from its mine bombardment and gunshot barrages. At the end of the pipe section you'll go through a small outdoor section, then back into some underground pipes for another loading screen.

Once it's over, carry on through and you'll see that the helicopter is thoughtfully waiting for you outside the pipe. Head outside and it'll begin harassing you with mines and gunshots again; just follow the canal along, and use the logs on the left as a ramp to get over the large concrete steps. Once you get to an open area, head right, along to the bridges. Carry on along the channels, using the sides to avoid some of the mines that land in the narrow water section. At the end, head left, and a short way later, head right. You'll come to a left-hand turn at the base of a crane; there's a wooden barrier on the right-hand side that will serve as a turning ramp you'll need to clear some of the debris around the corner, and make it onto the concrete balcony outside the large shed. Once up here, drive your airboat inside and on to the lift thing. Use the health dispenser and suit charger in the corner, then use the wheel to lower your airboat into the channel below. When it's down, hop down yourself and get back in. Head along the polluted channel and through the gate. In the large open area up next, some headcrab shells will be fired from the bank in the distance; these won't hurt you but they will knock down one of the large chimneys; don't worry though, approach it with enough speed and you'll drive straight over it. Carry on around the bend and you'll see another pipe up ahead, being guarded by yet another APC. Weave between its rockets and head into the pipe. Around the bend, you'll get another loading screen.

Past the barricade, go left and follow the junk-filled tunnel to a small rebel base gate. They'll let you through, so park up your airboat and head up the wooden walkway to meet your rebel friends, including a Vortigaunt who will greet you. Go inside, and you'll be given a small briefing on where you're going, and that you'll be getting a little more "firepower". Go outside and the Vortigaunt will finish attaching a combine machine gun to your boat, the same weapon that the helicopter chasing you is using to try and kill you.

|description=18. Collect the crate in the small shack.

|progress=18

Shoot the CP here, get off the boat and go right. Along here will be another lambda symbol and some supplies for you in the sort of shack up the ladder to your left, but you will be ambushed by a zombie and a load of headcrabs. Once you've got the goods and killed the enemies, go back to your boat and head left.

After the loading screen, carry on through to the  large open water-and-dirt section littered with rocks, where your old friend the helicopter will be waiting for you on the landing pad at the far end. Now you have the means to deal with it, so approach it and watch out for the various explosive barrels and nasty debris in the water. This time the helicopter will show absolutely no mercy and will drop ridiculous numbers of mines down to get you — it's pretty much a like a sprinkler, only the water droplets are mines half the size of the helicopter itself…that's strange. Where does it get the room? Anyway, it's also quite tough, it takes about five or six full unloads of your airboat gun to bring it down. Your best bet to maximize damage is to wait for it to start dropping mines, then wait for it to get close and run out before firing, as the spread of the gun is quite large.Once the helicopter is destroyed, head over to the gate below the landing pad. Climb up the ladder and turn the wheel to open the gate.

|description=19. Check out the waterline of the dock outside Dr. Vance's lab.

Leave the airboat behind momentarily and go across to the ladder by the wooden walkway. Climb up it and head across to the large barn/shed. Deal with the CPs inside and outside, and once you have you can raid the ammo stores in the shelves in the barn for pretty much maximum ammo for all of your current weapons, as well as using the health and suit recharger on the back wall. Head back outside once you're done, and around the back of the building you'll find a wooden walkway across to the dam/drain system that was originally on the right of the watery area where you fought the helicopter a minute ago. Once across, go along to the gate control mechanism and use the working switch to open one of the gates in the dam.
