Back in the real world (one story above your safe house in Naccarrapur, to be specific), Amita thinks it’s time to expand your territory . . . by blowing something up.
Amita’s truck
If Amita is in charge, she’ll send you to ambush and hijack a chemical truck. Once you reach the site, place two C4 charges in the road, spaced a few car lengths apart so one won’t set the other off when it detonates. Pulling a spare vehicle or two into the road will also help (but keep one aside to use).
As the convoy approaches, blow the technical in front with one C4, then the pickup in back with the second. This will leave just the chemical truck, which should be slowed by the wreckage. If you can’t shoot the driver outright, chase him down in your spare ride and use a vehicle takedown.
Sabal’s truck
If Sabal’s in charge, he’ll redirect you to a fuel truck at one end of a bridge, surrounded by two rocket-launcher sharpshooters, a mortar, and at least five regular soldiers.
A frontal approach is risky, thanks to the rocket launchers, the mortar, and the narrow bridge. Instead, slip up from the riverbed using the grapple point southwest of the bridge. By the time the bad guys see you, you’ll be too close for the mortar. And they’ll be a split-second from death.
The grapple near the bridge is okay, but the one under that lone pine tree on the left is even better.
The battle finished, grab the poster on the shed wall and hop into the fuel truck.
Min’s technicals will burst into hot pursuit the instant you take the wheel. The Vehicle Takedown skill comes in crazy-handy here, but remember to always turn and crotch-shoot the soldier at the rear gun turret after you’ve whacked the driver.
Also, consider getting out of the fuel truck to fight. It might seem counter-intuitive, but you can heal—the truck can’t. The roadblock around x:461 y:623 is a great example. Hop out, snipe the jerks blocking your path, collect the four green herbs nearby, and the end result is you have two more health syringes while the truck hasn’t taken a scratch.
When you reach the second roadblock (the one right before the bridge), stop and proceed on foot. You’ll have enemies at the roadblock, at the mounted gun nest further up, and also shooting down from a second nest on the small hill to the north. You don’t want them following you across the bridge.
Once you’ve cleaned them out, climb the hill and snipe the sniper in the tower across the bridge. Now you can slam the truck through the roadblock and into the barrier wall. Just be sure to bail out before the big boom.
Safe to say, this effectively eliminates the “stealth” option.
Royal Guard soldiers will fly out from the base beyond the newly destroyed wall like a swarm of angry bees. You run a strong chance of being overwhelmed here, so hug the walls to protect yourself from the mounted gun straight ahead, the mortar in front of the green hut to the east, and one of the sniper towers. This will reduce the likelihood of the Royal Guard surrounding you as you chip away at their numbers.
Hiding against the wall isn’t glamorous, but it might just keep you alive.
Don’t underestimate the Royal Guard. They’re tougher and better equipped than the Royal Army scrubs you’ve fought up until now.
Once the post is cleared, enter the mortar shack to broadcast the victory message and prepare for more enemies to arrive from the east. You could try to make your stand in the shack (or hit them with their own mortar), but it’s easy to get overrun. You may want to instead head up a sniper tower or simply return to your spot at the bridge entrance, where it’s easier to keep them all in front of you. The enemies are numerous, but the only ones you should really have to watch for are the heavy flamer and the pair of snipers.
After that, nothing left to do but loot the corpses and meet the Golden Path soldiers celebrating at the entrance. Congratulations! You can now access Northern Kyrat.
