A destroyed container is west of the tracks. Break the door and go inside. Inside, you will find a few resources and a journal. Use your lighter to burn spiderwebs.

The gas mask upgrade is in the chest located at the back of the container.

You can find the compass right after you start playing on the new map. This item will point you towards the current mission objective.
To get it, you will have to enter a plane wreck.
The compass is lying on the ground in front of the cockpit's entrance.

To use it, craft the compass by using a workbench.

There is an abandoned campus in the eastern part of the map. This is where you can get night vision goggles. They are lying on the table. You can see it from the distance thanks to candles. The night vision can be turned on and off whenever you want to.

It will help you navigate through dark locations.

A destroyed gas station is in the eastern part of the map. This place serves as a bandits hideout. You can eliminate them stealthily. After that, sneak inside the building. You will see the upgrade right after you enter the building (even though the room is dark).

To use the upgrade, craft it on a workbench.

There are two islands south of the tracks (they are marked in the picture above). You can get there by boat or on foot by walking on the frozen water. The small building has a machine that uses fuel. The machine is empty, find the right fuel tank to pour fuel into the machine. Go behind the building, you will find a full fuel tank. Pick it up and go to the machine. The next step is to go to the shed. Open it by using the handle next to the door. Go through the hole to reach the rooftop. From there, you can go to the next room. Start the generator. Then, go to yet another room.

You will find a corpse with a battery charge controller upgrade.

In Volga you will come across an abandoned building. Here you'll find an upgrade that allows to carry more ammunition. Additionally, you will be able to release slaves from there. To enter the building you have to quietly get to the top, by the stairs. There you will come across an open passage. Enter it quietly. You can see your opponent sleeping right away. Walk up to him and deafen him. This way you won't have to fight. If you want a spectacular fight, shoot at him and you'll summon the rest of your opponents.

Walk down the staircase and check the wooden chest. The upgrade lies on it.

In Volga, near the rail tracks, you can find a bandit camp. On one of the tables you can find the helm upgrade.

Two bandits stand next to it. Kill them and take the item.

Metal detektor is located on the Island in the southern-east part of Volga. Don't go in the direction of a huge building. On its right side you will see a small house.

In it, on the table, among the clocks, you can find a metal detector.
