Work Pass
Move to the left side of this new area and speak with Shurik. Dont worry about the riot guard; he wont bother you if you keep in line. He forgot his glasses in the mines. Agree to help him out if you wish.
Optional Objective (Shurik): Bring back Shuriks glasses from the mines.
The center door in this area is a small control room containing a med cartridge and a pack of smokes. But the riot guard wont appreciate you breaking in with your stolen keycard. Wait until the riot guard looks away if you want to use the keypad to enter this room. Find pack of smokes #34 inside. When you leave, peer out of the door and wait until the riot guard looks away or hell open fire.
Go to the door on the right side. Use the keypad to unlock the door. Enter sneak mode and creep inside the room. Hide behind the tall crates ahead. There are several guards in here but theres a problem with the lights. Perfect opportunity for sneaking around with the eyeshine!
When the lights are out, sneak up the stairs on the right side of the stack of crates. With eyeshine on you can see the guards facing the other way. Go toward the right corner and spot the loose panel. Open it and find some UDs inside as well as half of the snitch-list that Cuellas is looking for (Solving Cuellas Mission Part 1).
Look back at the rooms center and the guards. Once the lights switch off again, scurry across the room in sneak mode to the opposite staircase. Go into the right corner near the grating and hide behind the crates. You can open this grate and find some UD money inside. When the guards arent looking and the lights are out, hug the wall to the opposite corner of this platform and find the other grate. Crawl inside. This can be a tough section since you dont have weapons. If youre spotted, get quickly to the exit grating and scamper through.
Navigate the vent shaft, climbing the ladder, and rounding corners as necessary. Continue until you emerge on top of an elevator. Dont drop inside--there are guards! Stay on the top of the elevator into the next section.
Mine Entrance
Objective: Find Jagger Valance.
Watch the guards exit below. Instead of dropping down inside the elevator, leap onto the top of the ventilation shaft and find the hatch. Open it up. Go right and follow the shaft to the grate. Look through the grate and wait for the guard to move away. Bust out of the vent.
Use the stack of crates for cover as you navigate toward the left side of the hall. Wait for your opportunity to use sneak mode to get behind the guard and break his neck. Drag him into the dark ventilation system. Go down the hall until you spot the vent shaft overhead. Use it and navigate the vent system. When you reach an intersection, take the left path to find pack of smokes #38. Dont bust out the grate here cause it just leads back to the previously explored hallway. Continue through the unexplored shaft to the grating. You should spot crates ahead.
Duck into sneak mode within the stack of crates. Look out to the right and spot the guard. Hes standing over a fan system. Walk up behind him and push him into the fan. Back out and use the service panel in the rooms center to disable the lights and fan. Search around the crates for some money then go to the fan and drop down onto the blades.
There are guards at the bottom. Work quietly and wait until they move away. If youre seen, just run! Go through the door and toward the next section and just ignore those pursuers.
Security Checkpoint
Go through the large door. Spot the guard in the distance. This is a tough area, particularly because you have no weapon and cant use the assault rifle discarded by disabled guards. When all else fails and you are seen: run!
Sneak along the left side of the large area and stick behind the crates and darkness in the corner. The right side of the area contains a riot guard and a couple normal guards. None will greet you with open arms so do your best to remain out of sight and in the dark shadows.
There are two routes through this area: an upper and lower route. Both have their difficulties. For the upper route, go to the back corner behind the crates. When the guards are talking and looking away, hop up onto the ledge in the corner. Stick along the left side and maneuver underneath the hangrail ahead. Cross it to the far side and drop down onto the crates.
Pull yourself up onto the crates then hop over the high railing to the upper catwalk. If you want a nearby pack of smokes, jump to the middle section overlooking the room below and use your eyeshine to find pack of smokes #39. Return to the catwalk and go down the stairs into the upper mines.
