Walk toward where the enemy stood and the floor breaks under your feet. Return up the ladder and jump from the broken floor through the window and into the adjacent room. You can cross the broken area and use the medkit if needed. Pull the lever inside the room; this opens a door on the ground level beneath the ladder. Drop down and continue in that direction.
Follow the tunnel to the next room. The toughest foes wait behind the crates. Spot a sniper up high and another guard behind the fence. After clearing the room, use a radio-controlled bomb on the cracks on the right side of the chamber.
Theres a medkit to use to the left. Your eventual goal is the far left side where youll place another radio-controlled bomb. Before doing so, however, jump onto the crates on the right side and break open the grate. Shoot the guard ahead and drop into the room. Beware of two more guards to the right that will ambush you if you arent careful. Comb the room; it contains weapons, ammo, grenades and armor. The tank opens a hole in the wall. Return through and detonate another radio-controlled bomb on the crack to the far left.
Use the blowtorch to bust open the lock on the left. Move around to the right and find another spot for a radio-controlled bomb. Place one and detonate. This opens a hole in the grate below. Hop down into the water and follow the crawlspace to the new weapon at the far end. Return outside the crawlspace.
Retrace your steps through the mining facility. Some new guards appear so what your step. Furthermore, the mining facility is collapsing so some rooms may be a bit different than you left them. For example, navigate the right side of the hole in the floor. On the far side youll find another spot for a radio-controlled bomb (you passed here earlier). Detonate the bomb.
Move through the open passage and shoot the enemies that attempt to block your advance. Search an alcove on the right for additional ammo and make a stop at the medkit if necessary. Follow the hall into a kitchen and finally into an open office area. Eliminate the guards inside. Go through the left gate to the computers. Use the one marked "Locked" to trigger the next event. Gas enters the room. Theres no escape. Youve been captured!
Objective: Find way to escape from prison cell.
Crouch and break the bricks in the corner to find a secret room. Pick up the knife. Return to the cell door and press the "use" button to start beating on the door. Do so until you attract the guards attention and he walks over. When he opens the door, kill him using the knife (secondary attack). Pick up the weapon on the left side of the room and eliminate the other guard. The far door opens revealing more hostiles. Shoot them (hit the red barrel for added explosive damage) and grab the weapon, ammo case, and armor. Move along the top of the shelf on the left side of the room. From here you can leap to the ladder. Climb up and into the room above.
Grab the grenade off the crate. Jump onto the shelving on the left side of the room. Next, leap to the top of the file cabinets. Break the grate with a weapon and drop through. Youre now in the room that contained the gas. Eliminate the guards and move through the open passage on the right side. Follow the hall down the stairs to the left.
Note the open hole to the right. Your allies are just outside and about to mount an attack on the compound. Defeat an enemy to the left then assist your allies through the valley up toward the compound. Defeat the enemies around the perimeter then go inside the building. Shoot the guards inside. Grab the flashbang and drop down through the hole in the floor. More guards occupy the lower level. Maneuver back outside and eliminate the sniper on the adjacent rooftops. Your allies bust through to assist. Watch for additional enemies to the far left.
Objective: Escort hostages to rescue zone.
Cross the courtyard to the far left side. Theres an open passage here. Shoot the red barrel to cause a damaging explosion. Eliminate remaining guards and find a pilot in an adjacent room. Defeat the guards then escort the pilot back to your allies.
Another door opens on the right side of the courtyard. Assist your allies in eliminating the enemies that appear from the passage. Enter the next structure. Move to its rooftop. Follow the edge of the roof from building to building until you can jump over the fenced in area that contains a health pack. Theres also a hole in the ground here.
Follow the tunnel to another hostage. As soon as you rescue him, an enemy enters the room. Defeat the enemy and follow the tunnels to the exterior. Combat the enemies that appear on the right side. Escort the hostage to the rescue zone to the left to complete the mission.
