Part 17

When encountering mines, stop ahead of them and use the Gravity Gun (GGP) to move them into the water.

In Half-Life 2 (HL2), squeeze between the house and the end of the boulder. In Half-Life 2: Deathmatch (HL2ud), the boulder splits, opening a path on the left.

Save your NOS (Nitro) boost for later. Drive past the boulder using the available path for your version of Half-Life 2.

Beyond the boulder, you'll find debris, cars, and more boulders. Move to the left side of the road near the rock wall.

Just before car #1, activate NOS to push it aside. Drive into the gap left of the truck.

Jump over the low side of the massive boulder, potentially taking out some Breen Grenadiers (BGs) along the way. Keep driving away from the chaos.

A vehicle and debris blockade appears near a knob hill. Maneuver to the right and between the blockade and the knob with the buggy.

Climb the hill; you will find an ammo case (SC) and a Combine Ball (CB) on the hill. Ahead, you'll see a bridge, a security station (SS), and buildings. An Overwatch Border Guard (OBG) is on the walkway (Wkwy) of a road sign, with two more advancing from the buildings toward the bridge.

Grab the Combine Ball (CB), crouch, scope it, and wait for the two ground BGs to stop.

To clear the three bridge area OBGs, start with the barn BG, then the bridge BG, and finally the sign BG. Aim for the bolt just left of the top left corner of the end bridge post closest to the barn. Send the bolt as the BG clears the security station (SS) tower en route to the barn.

Sending a bolt to the explosive barrels (EBs) at the gas tanks may eliminate all three OBGs involved in the flanking maneuver.

Sprint between the shed and garage, then circle the garage clockwise to its rear corner.

Past the garage, turn right, scope the CB, and send a bolt to the EBs near the gas tanks as the BGs pass. This prevents their flanking maneuver.

Backstep towards the rock wall, crouch, and select targets as they become viable.

When all BGs (often 5) are down, cautiously approach the house from the left to check for any remaining enemies.

Use the Gravity Gun (GGP) on the generator truck to separate the power to the security station (SS).

Sprint back to the buggy and drive off towards the bridge.

The Bridge: This section requires careful navigation to avoid falling or self-destruction.

RR TRACK SS CR TO RAZOR TRAIN (12/29/16): New tactics begin at houses #1-3, involving entering and exiting the bridge area.

New maneuver to shack#3 before GS#3 (1/4/17): This is a fast and safe method to complete the bridge with minimal deaths or restarts.

Pull up to house #1 (on the right), then back up just past the shed and target the house doorway. Use the Tau Cannon to eliminate Overwatch Border Guard (OBG) #1.

Exit the car and enter house #1 from the left side of the door in a crouch, using either the Riot Gun (RT/SG) or the Pulse Rifle (PR) for OBG #2. Exit or clear the back room.

In HL2ud, you may encounter 1 or 2 OBGs from the left as you exit house #1.

In the car, drive straight to house #2 (the large house), then back up to your previous position. Three more OBGs appear from the garage of house #2, house #2 itself, and house #3. Eliminate them with the Tau Cannon.

Instead of backing the buggy between the garage of house #1 and house #2, back it into the niche between house #1 (East Perimeter side) and the red shed.

Sprint to the entryway of house #2. If you used the launcher extensively, reload at the Local Ammunition Cache (LAC) then head to the second floor of house #2.

Use the small end table near the stairs. Remain at the top of the stairs, scope, locate, and use the Gravity Gun (GGP) on the Combine Ball (CB) from the nearby room, then head back outside.

Sprint on, along and to the end of the wooden walkway (Wkwy). At the Wkwy railing, beside house #3, and facing the entry to the Bridge abutment, jump up onto the railing.

Look left to locate the path leading to bridge abutment #1 East Perimeter (EP), then run/jump to the path. Sprint to the EP and enter, load up on supplies, then use the Experience Points (XP).

Continue to and through tower #1 to tower #2. There is a LAC in the base. Climb the stairs to the top (there are 2 more Sentry Guns (SBs)).

Exit tower #2 through shack #1 to the metal walkways (Wkwys), then make your way to shack #2. Ignore and continue past shack #2 and ignore shack #3 ahead and below.

You need to find a way to get to shack #4. Move to the end of the broken Wkwy, scope and look straight across and over shack #3.

When you've found the path and are standing on the Wkwy leading to shack #4, sprint through it. There are 2 Heavy Combine (HCs) to the left of the EP.

When back outside, you will see shack #5 ahead, attached to tower #3, similar to shack #1 and tower #2.

Turn right at the EP to shack #5 and go to the railing. Look up and left to see the top of a Combine lookout station. Shoulder the CB and jump onto the railing. You now have Line of Sight (LOS) on the lookout. Eliminate OBG #1.

If the OBG throws a grenade before you eliminate him, quickly retreat into shack #5 for cover (press the cover button to crouch behind walls or objects).

Go down through tower #3 to the Wkwy, sprint to the beginning of tower #4 and crouch. Creep forward; OBGs #2 and #3 are on the right, one low and one high.

Eliminate one of them with the CB, then back up for cover while you reload. Relocate and eliminate OBG #3.

Switch to your pistol, then sprint to and through the EP.
