Solving Jamal-Udeens Mission and Cuellas Mission Part 2: When you move through the door, youll encounter three blueskins--including Mosely. Hes not so friendly this time. The other two are Alonzo and Void. Defeat them. You have the tranquilizer gun so an easy way is to run away from them, turn around, and shoot them with the gun. Stomp on their heads to finish the blueskins off. When you stomp on Voids head, he drops the second half of the snitch-list that Cuellas is searching for.
Return to Cargo Transport and go to the top floor. Move through the door ahead. Time for another little tangent for a pack of smokes. Go around to the right and find the stack of crates. Climb them. You should be able to see the top of the vent shaft that runs along the ceiling. Jump onto the shaft and return toward the other side of the room. Drop onto the shaft where the two pieces are separated.
Follow it to a vent shaft and drop inside. Enter sneak mode and exit to the right side. Spot the guard ahead. Sneak up and kill him. Speak with Valya. He gives you the code to his chamber.
Optional Mission (Valya): Find Valyas secret chamber.
Return through the vent shaft and back to the previous room. Drop off of the shaft and use the vent hatch near the floor. Navigate the new shaft. You emerge out of the shaft into what looks like a precarious chasm. Drop off to the right side. Then turn around and look down to find another landing spot. Drop down and move into the new vent shaft.
Solving Valyas Mission: Navigate this shaft until you find a vent hatch above you. Climb out. Youre back at the elevator. Drop inside the elevator and exit through its main door. Maneuver across the large expanse. Arm the tranquilizer gun so you can disable the two guards that will impede your progress. Use the keypad to open Valyas chamber. Inside find a health station and, on top of the stack of crates, pack of smokes #37.
Return to the elevator and hit the keypad to ascend. Exit the lift. Now you can return to the prison area and complete some of your quests for their rewards. Exit the lift to the left. Bust through the grate at the back corner of the room to find pack of smokes #36.
Climb onto the crate to the left and grab onto the ledge. Spot the riot guard below. Shimmy to the left side and use the hangrail above. Traverse to the opposite side from the riot guard and drop down. Youre now inside the Work Pass area. You can even see the riot guard and Shurik below. Drop behind the riot guard then walk up to Shurik (the riot guard wont bother you). Talk to Shurik to return his glasses.
Return through the door and back into the Recreational Area. Speak with Twotongue and purchase pack of smokes #23 for 20 moths (if you need more, find them throughout the Recreational Area). Continue through the area and find Wilkins and talk to him to complete his mission. You receive some UD money as a reward. Talk to Jamal-Udeen to finish off the blueskins mission. Hell hand you pack of smokes #24 as a reward. Go to the Feed Ward and speak with Cuellas to complete his mission.
Return into Work Pass and enter the door on the far right (Power Central). Theres a guard in the back right corner of the room. Take him out from long-range with the tranquilizer gun. Use the nearby keypad to enter the door into Feed Ward Emergency Ventilation.
Enter the vent hatch on the right and start navigating the tunnel. Arrows and writing inside the shaft point the way. Move toward the Feed Ward. Drop through the grating and go into sneak mode. A guard patrols this hall. Sneak up behind him and eliminate the guard with the tranquilizer gun. Or you can avoid him and enter the door on the right side of the hall.
Time for a brief pack of smokes hunt. At the intersection, go left and quickly use the grating. Crawl inside the vent shaft. Follow it to a right turn and go through. Emerge out into another hallway. Go to the right and grab pack of smokes #43. Return through the vent to the room with the intersection.
You may spot guards patrolling the room. Deal with them with your tranquilizer gun. Dont forget you can shoot out lights as well. Go to the right side of the hall and use the service panel to disable the areas lights. Continue to the left and disable more guards. Shoot out the lights with the tranquilizer gun.
Hug the left wall until you reach a split in the path. A guard patrols to the right. Take him out. Continue along this path and eliminate any additional guards. Locate the vent hatch in this area and crawl inside. Follow the arrows toward Tower 19.
