(4) Aggressive solution: Retrieving the package from the shed Deus Ex: HR Guide
Last update: 11 May 2016
Map legend: 1 - Main port gate; 2 -- Transformator with electric discharges; 3 - Hole blocked by crates; 4 - Guardroom with a terminal and a switch; 5 - Guardrooms with terminals; 6 - Descents to lower paths; 7 - Warehouse with tools and a first sniper; 8 - Main warehouse and a second sniper.
It would be good to attack Belltower soldiers before you enter the port area, right after you leave the sewers and get close to the main gate (screen above). The main advantage of this method is that opponents won't be able to open an entrance from their side so you do not have to worry about their surprise attacks.
In addition to soldiers there may also robots appear near the gate #1, but you already should know how to deal with them (I personally prefer EMP grenades). After clearing out the area, get to the other side and start eliminating opponents present in this location #2.
During your fight here you have to watch out for two snipers, which should be killed fast. A first one is located on the tool shed roof, which is your current mission goal #1. You can try to attack him from a lower level or use a ladder to reach him directly #2.
Second sniper patrols one of the balconies of the large warehouse, north from here and he is a greater threat, because he can attack you for a very long distance. So I suggest not staying long in the open area. A mentioned sniper is best to be killed with a sniper rifle #1. If you do not have such weapon, then return to the tool shed and take a weapon of the sniper you've just killed #2.
A current target of your mission now is the tool shed. You can choose a main entrance #1, but this is advisable only if you secured the area. Otherwise you could opt for breaking down the western wall of the building #2, using the Punch Through Wall augmentation.
Go to the southern room of the warehouse and interact with a locker #1 marked by the game. You need to take out of it a Tong's explosive package #2. Tong himself will contact you after few moments, explaining that after settling all matters in the port, you should plant a bomb in administrator Wang's office.
Reward: 1000 experience points.
