Crysis PC Game: Crysis PC Game - Walkthrough: 06

Proceed to the Landing Zone Next to the Crusher

Now it's finally time to see what the big mystery is all about. Head up the road to the left. A fresh quake hits, causing a sonic boom to blast past you. The mountain ahead seems to be coming apart, revealing a glowing blue-and-white structure apparently buried beneath the rock.
Secondary: Infiltrate the Office and Retrieve the Hostages

Move toward the mining complex straight ahead. Begin your assault by blowing up the explosive barrels on the back of the truck waiting to enter the compound. Cloak and dive into the weeds on the right side of the road. Snipe the soldiers manning the machine-gun nest and the watchtower. Then spin around and take care of the KPA coming out of the jungle behind you.

Cloak and enter the mining compound. Restock on ammo in the first building on the right. Consider swapping out the gauss rifle for the shotgun if you still have the gauss, as the former is far more effective in close quarters and has a faster firing rate. Be sure to pick up a missile launcher here for use against the North Korean tank patrolling the grounds. Grab another missile launcher once you use up the three shots of the first one on the enemy armor.

Proceed to run-and-gun through the rest of the KPA here. Duck into the buildings and behind cover when you need to regenerate suit power needed for the cloak. North Korean intel can be found in a building to the right of the main gate. Blast the KPA goons on the stairwell with your shotgun. Head upstairs into a big computer room and use the laptop in the corner to download the required information for Major Strickland.
Proceed to Landing Zone (Again)

Now get back to your main mission. Go to the back of the base and switch on maximum strength to vault the wall and razor wire. Walk a few feet through the jungle and drop down to a big industrial mining complex and rock crusher. This area is loaded with KPA, including a couple in nanosuits with a new weapon—a pretty devastating minigun that can shred you in seconds if you're not careful.

Begin by climbing up the hill right in front of you. Cloak and snipe some enemies. Try to kill at least one of the nanosuit soldiers, who should be standing on the closest conveyor belt. Take your time here. Be patient and wait for the KPA to reveal themselves, and snipe them from long distances as much as possible before engaging them directly.

After things settle down a bit, leave the hill and move to the left, where a number of objects can be used for cover. Be sure to keep a good distance from the explosive barrels and the big propane tank, though, as a couple of bullets sent your way at the wrong time can turn your lights out in a hurry.

Cloak and hop from one object to the other, gradually making your way to the refinery. Snipe the guards manning the machine-gun nests on the upper level of the building and the other soldier on the roof of the building to the far left. Keep an eye out for the other nanosuit-wearing KPA. When you spot him, cloak and get as close as possible, then hammer him with the shotgun until he drops. You can also sneak by everybody and climb the steps to the machine-gun nests, which can of course be turned against the KPA on the ground below.

Yet another North Korean assault chopper joins the party at this point. Knock it out of the sky with a couple of well-placed shots from the missile launcher. If you don't have a missile launcher, run to the far end of the crusher building and climb the steps. At the very top is a minigun and enough ammo to blow the whirlybird apart.
Infiltrate the Mining Complex

A pair of VTOLs arrive to mark the clearing of the landing site. They don't actually send out any troops to help you, of course, although you can hop in them for more gauss rifles and ammo. Whoopee.

Major Strickland now orders you to enter the mining complex proper. Check your map and make your way down a dirt track. Keep cloaked as much as possible. Run up to the KPA that approach and kill them with your shotgun.

You soon enter a mining quarry where a North Korean tank is patrolling back and forth. Go to the far end of it, then drop down to the pit floor where there are a lot of trailers and other objects that can be used for cover. Shotgun the two KPA troops by the truck directly in front of you, then creep forward to a stash of missile launchers on a crate under a camo cover. Terminate the tank with extreme prejudice, then grab another missile launcher.

Move on to another pit with features similar to the first. First, empty your new missile launcher on the North Korean tank found to the left near a group of trailers. Then cloak and slaughter the KPA grunts in the vicinity. As this will be close-range combat, feel free to fire up your shotgun. Scrounge ammo from the dead soldiers and a trailer after the smoke clears. Be sure to grab a missile launcher from one of your victims before leaving the scene.

Climb out of the quarry past the barbed-wire fence. Next up is a huge battle at the North Korean fortifications set up at the mine entrance. There are a couple of machine-gun nests and at least two nanosuit soldiers with miniguns here, all dug in behind concrete blocks and trenches. Thankfully, you can cloak and use these trenches for cover to get into shotgun killing range. As before, try and engage the nanosuit-wearing KPA from close distance with your shotgun. That way they won't even get the chance to spin up their miniguns.
Locate the Hostages

Enter the darkened mine. Flip on your night vision for a better look at the place, which seems to be falling apart. More nanosuit KPA are just inside with miniguns. Cloak and get close to play more sweet shotgun music. Swap out your shotgun for a minigun here if you're running low on shotgun ammo, as you won't find any more for a while.

Wander through the tunnel to an elevator shaft, then drop down to the lower floor. Go past the sparking light and down the tunnel with rickety floorboards. Cross a big cavern and hit maximum speed as soon as you hear the rocks falling from above. Zip forward and to the right to avoid being crushed instantly by the avalanche, then leap over the chasm.

Listen to voices up ahead. Sounds like the enigmatic General Kyong and his hostages. Watch a bit of the argument between Kyong and a young woman who must be Rosenthal's daughter Helena. Enjoy being knocked out and dragged to an audience with the general where he smacks you around. Hmm, he's a bit of a megalomaniac, isn't he? Take in the not-so-shocking murder and a blinding light show.

Eliminate General Kyong

Boss battles don't get much easier than this. Right after the electrical surges demolish the chamber, General Kyong grabs a minigun and attacks you. At this point, however, your suit comes back online, so all you have to do to avoid taking any damage is click on your cloak.

Lots of weapons and ammo litter the floor of the chamber. Grab an SMG right in front of you, then move forward to the darkened space behind Kyong. Stock up on ammo here, then kill the general with a steady stream of gunfire. Being on a slightly elevated landing seems to prevent him from seeing you even when your cloak is off, so you should be able to kill him almost instantly.
Evacuate the Hostage

After Kyong meets an untimely end, Helena Rosenthal waves you over to an elevator. Join her and she tells you about a way out. Unsurprisingly, the elevator jams en route to this unexciting departure. You call down a VTOL for a rescue, but it can't get close enough for a proper pick-up. While Helena leaps to safety by hurling herself out of the elevator and into the waiting arms of a dangling American soldier, you're out of luck. As the VTOL flies away, you ride the plummeting elevator back down to the cavern floor you just escaped.
