Reaching The Gate
The level will start you at the end of the street leading to the Brandenburg Gate. In the building with blue shutters ahead, you can snipe an enemy on the second floor. Time you shot with the explosion so that you can stay in stealth.
Now, walk along the right side of the street up until the set of stairs. Turn around and look at the building behind the underground sign. The enemy up here will walk out of your sight and back into it. Wait for his patrolling path to line up with an explosion to take a shot at him.
Walk behind that underground entrance and the tent just after it. Use your Welrod on both the enemies standing next to it.
This will cause the rest of the enemies to become alerted. However, this is helpful as you can use this tent as cover and snipe the majority of enemies from afar. A couple of enemies will head to the dilapidated building in the centre of this area.
Watch out for the enemies on the main street as they can easily pile up next to each other. There are also two mounted machine guns here.
Once everyone is dead, it is time to collect the Gold Bars and Bottles here.
From the starting location, head down into the underground entrance. Crouch to fit underneath and find a Gold Bar about halfway along.
Head outside and up to the machine gun nests at the end of the street. Sitting on a table to the left, you can find a Hidden Bottle.
Enter the building on your right and pick-up the Gold Bar from the table in the right corner of the room.
Continue into the next room to find the third Gold Bar on the ground, to the side of the stairs.
Make your way upstairs and head into the room on your right. Lying next to the piano is another Gold Bar. This one can be a little tricky to pick-up. Just wiggle around and prone as much as you can. You will eventually pick it up.
From that Bar, head outside through the hole in the wall and look at the car ahead. Lying inside it is another Gold Bar.
Follow the objective marker into the next building. Head upstairs and look out towards the arena ahead. On top of the central pillar, you can find the second Hidden Bottle.
Walk forward and a little to the left. Look to your right at the Gate. Next to the horse statue at the top, you can snipe the final Hidden Bottle. This will give you the Jungle Juice trophy provided you have shot all the bottles up until now.
Reaching The Vantage Point and Executing Wolff
Head through the house and jump down to the street level. You can shoot the fuel cap on the tank ahead straight away.
The enemies will become alerted once you do this. Snipe the few who are on the left side of the map. There are a few snipers located in the buildings around the area. They spawn randomly, so keep an eye out and stick to prone or cover.
Once the soldiers in the surrounding buildings have been cleared out, push out to the centre of the courtyard. Take cover and face towards the Gate. Enemies will pop out of cover from behind the sandbags in the very back of the area. A second wave will spawn once the first dwindles in number.
Once the music dies down it is time to get the final Gold Bars.
From where you dropped down into this courtyard, head to the left side of the street and into the first door. In the hall, behind the door, you can find a Gold Bar.
Make your way past the tank you destroyed and to the green tent next to the back building. Inside, resting on a box, is one of the remaining Gold Bars.
Push up to where you killed all of the enemies. Head through the door on the right side first. Go upstairs and pick-up the Gold Bar from the floor.
Make your way back outside and follow the objective marker into the left door. As you enter, look on the table to find the ninety-ninth Gold Bar.
Climb up to the top of the gate, following the objective marker. As you get close, Wolff will start to escape. Before you shoot him at the top, look on the left edge of the platform to find the final Gold Bar.
Now turn and aim towards Wolff who is driving away in a vehicle. Aim your shot by holding your breath and take him out to complete the level.
