Upper Mines
Note about the mines. You’ll encounter the same moths you found inside the Recreational Area. If you want another pack of smokes from Twotongue, collect each moth you find until you have 20. If you can’t quite get to 20, you can get more in the Recreational Area when you return but get as many as you can.
Arriving from the upper catwalk, enter sneak mode, move forward and hug the left wall. You can see guards on the opposite catwalk so move carefully to avoid detection. Go around the left corner and continue along the catwalk. When you spot crates below you to the left, drop down and hide in the shadows.
Move out to the left and look for any nearby guards. If you spot a guard, disable him and drag him into the shadows. Move across to the crates on the other side. Stick within the shadows. Wait for the guard to pass and scamper to the back corner to find a narrow path on the right side. Go up the stairs and through the doors.
Cross the catwalk hugging the left wall. Enter sneak mode and move through the next door on the left. As you move into the hall, spot a guard with his back turned to the left. Sneak up on the guard and disable him with a neck break. Speak with the other guy: a blueskin named Mosely.
Turn around and creep around the left corner toward the next door. Peer down the hall and wait for the guard to move to the balcony on the right. Sneak behind the guard and disable him. Snag the security card. Look in the right corner of the balcony for pack of smokes #40.
If you want to recover Shurik’s glasses for his mission, they’re nearby.
Solving Shurik’s Mission: Exit the balcony and go right through the next door. Quietly approach the next balcony ahead in sneak mode. There are guards and miners below. Go to the left side of the balcony and wait for the guard to turn away. Slide down the ladder and take cover behind the crates. When the guard looks away, sneak up and disable him. If you’re caught in action, fight him hand to hand. Try and grab his weapon and disable him.
Speak with the miner here named Quintana. He inquires about Shurik; apparently Shurik’s glasses are nearby. Walk over to the crates in the corner and climb up to the top. Grab the glasses off of the top crate.
Return to Mosely and use the keypad to open the door behind him. Move forward into the next section.
Cargo Transport
Move along the right wall to find a pack of smokes on the ground. It’s pack of smokes #42. Utilize the health unit here if necessary. Face the lift system to the left of the health unit. Note the lights going up and down, which indicates the path of the lift. Hop on the lift going down.
At the bottom speak with Armadaro. He has a tranquilizer gun and he’ll sell it for a paltry 50 UD. Finally a weapon! The great news is that the tranquilizer gun has unlimited ammunition and can also shoot out lights and laser traps. Things just got a bit easier. Continue through the door and into the next section.
