Under the Radar

Under the Radar is the fifth chapter of Half-Life 2: Episode Two. It details the second half of Gordon Freeman and Alyx Vance's car ride to White Forest.

Walkthrough
Walk into the garage, then up to the second storey room. Drop some of the cinder blocks through the hole before dropping down yourself. Rip off the wood on the window. You should have more than enough objects to kill the Zombies with, though more will appear from the sludge. Once they're dead climb through. First head over to the sludge and jump over to the furthest car. It will sink so you have a limited time to grab the supply crates. Next head over to the upended truck to the left, climb up and through the window. Look right to see what you're up against. Open the door on the left and drop down, beware the sludge. The Zombies here will generally ignore you if you avoid them. Head straight forwards and then duck down right underneath a gap in the fence. Keep crouching from now on. Head straight through the pipe ahead, be ready for a flaming Poison Headcrab. Bear right. There is a turret ahead to the right, stay in cover and lob grenades at it. Once it goes down crawl on towards the building ahead and smash the window. Defeat the soldiers in here, head out through the door and then crouch left through the back door of a car. Follow the torso (watch out for another which will close in behind you) into another car. There's a tough little battle here where you're trapped in the car by two soldiers and a Fast Zombie, use the Pulse Rifle or the Shotgun. Crawl out to the right, keep going to the right side of the building.

Head right to the end first to deal with a Zombine, then chuck a grenade into the back of the truck with the grenade cache to kill a Poison Headcrab. Climb onto the truck and then up onto the roof. Chuck grenades through the windows at the Combine inside to your hearts' content. Once most of them are dead, drop through with the shotgun and deal with any survivors. Head to the autogun at the front of the building. Press the button on it to open it up, then drop a grenade into it and step back. Crawl through the hole you just created, help kill the rest of the Zombies and head back to Alyx. Go back inside the garage and get back into the car. Once the gate is opened drive out and turn right at the end.

Plow through the Zombies, turn right. The first radar blip will go, it will direct you to a car in the middle of the road with supplies inside. Set off the half-buried barrel on the other side and with some niggling with the Grav Gun you should be able to get the stuff inside. Get back into the car, drive on, turn right at the end. Your radar will pick up two more signals as you pass the corner of the large building on the left. Stop here, crawl through the car which has crashed into the building. Bring the metal cover down inside, roll a grenade under then quickly step onto it. It might take a few goes but eventually you should get up to the balcony. Turn the power off, drop down to get some serious goodies including the RPG. Head back to the car and then head into the supply depot opposite. Smashing into some crates in front of the metal shack at the far end should avail you the other supply cache. Get back into the car, get back onto the road and head into the tunnel.

Keep going until you reach the blockade, turn left up the steep mountain road. Your radar will go about half way up, you're looking for a cave on the left which has been blocked up with rocks. Inside you'll find health and a single, precious pulse grenade. Hmm, wonder why they're giving you so much stuff? Get back into the car, bear left until you reach a petrol station blocked up with cars (just before this you may catch a sighting of the G-Man heading into the White Forest Inn below). Punt them out of the way, get back in and head on down the winding road. Ride through the White Forest Inn...

Get inside the Inn as fast as you can. You should have plenty of Crossbow ammo and there's some in the basement, get up onto the second floor and pick off the soldiers through the windows. Move around so you can get new angles on them. If you need a reprieve go down to the basement, it's the only place that can't be fired into from outside and it's easily defended. After you've killed a few the Combine PA will sound and two Combine Elites will lead a squad inside from the front, make sure Alyx doesn't get killed here. After this three Hunters will charge in from different angles. Use the Pulse Grenade on one of them. Use radiators, explosives and anything else that comes to hand on the other two. Once you've defeated them you'll be able to leave through the back door one of the Hunters blows up to get in. Remember to stock up on supplies, there's plenty dotting the Inn. Careful of a final soldier on the roof of the building opposite.

You need to switch the forcefield off. Head with Alyx back up the road. Five more soldiers and another Hunter wait for you at the top of the hill. Pick them off with Magnum and Crossbow, there should be a gas canister and a big piece of wood here to deal with the Hunter. Once they are dead go up to the buildings, which are opened up now. Head into the one on the right, quickly sprint to the right to avoid the turret. Go into the room ahead, use the Grav Gun to knock the turret over. Alyx will then shut the forcefield down temporarily. Go into the room with the turret and it will snap back on. Ignore the door on the right and knock down the ladder to the side of it. Climb up, knock the debris out of the way and crawl forwards to the far end of the roofspace. Kill the Poison Headcrab to the side, then jump up and advance over the pipes onto the room containing the Energy Orb. Drop down on the opposite side behind the forcefield. Knock away the debris in the corner to reveal a vent, batter your way through into the Orb room. Open the door with the button, then punt the Orb through it. With this done open the door again, and head outside. There's some supplies in the building opposite. Head down to your car again and drive on.

At the bottom take a sharp right and turbo over the ramp directly ahead. Follow the road around. Your radar should sound for the last time. Stop when you're level with it, go behind some rocks to find an arrow pointing up. This is a game of chance really; you need to punt rocks and wood at the hanging basket to make it rock hard enough to make stuff fall down to you. It's worth it though, batteries, Magnum ammo and another Pulse Grenade. Once you're done get back in the car and head into the tunnel.

Bear right where the crash barrier has collapsed. Head down and left, leave the car in front of the concrete block. Step over and walk up to the crashed Dropship. Enjoy the next sequence, and then go back to your car and drive it through when Dog lifts the barrier. Up to you whether you race Dog, it's a fairly easy achievement to get. Turbo ahead of him in the stream, bear right up the slope, veer left and then right again, turbo-ing at the end should do it. Stop at the bollards, head inside the base and you're done.
