How to get a Riemann Integral-A vector SMG

A-integrals are the in vectors Stalker 2: The Heart of Chernobyl and they are one of the best machine gunners when it comes to having a very high rate of fire. Among all the weapons in the game, machine guns in general are quite versatile in dealing with enemies at close to medium ranges. The game can spawn enemies, especially bloodsuckers, out of nowhere. It is therefore better to always have an SMG with you such as the special variant of the Integral-A, the Riemann, equipped to tear an enemy to pieces in a few seconds.

How to get the Riemann Vector SMG in Stalker 2

Players can find the Riemann Vector SMG in the Journalists' Chest located in the Rostok region Stalker 2. You can find the cache inside an abandoned Rostok base right between the Volkhov Sam and Buryakivka areas. Here's how players can obtain the weapon.

Reach the journalists' escort and recover Riemann

1. ​​​​​Enter the Rostok base from the main entrance and turn left.
2. You will come across a room full of gravitational anomalies. So, make sure to equip bolts to disable them.
3. Make your way safely through the gravity anomalies towards the end of the room.
4. You will see the journalists' hideout on the right side, near the beds. Open it and take the Riemann Integral-A Vectored Submachine Gun and some ammo.
5. Now use the bolts to exit the room safely.

Now players will finally have the Integral-A “Riemann”, one of the best SMGs around Stalker 2: The Heart of Chernobyl. Players can further improve its performance by having it upgraded from the Tech Diode in the Slag Heap.

Solve the security code puzzle

In addition to the Riemann, there is also a code-locked safe on this floor. The code is divided into 3 parts and can be found on the bodies of three soldiers in the area. Here's how to crack the safe code in Rostok.

1. Take the first part of the code from the body of the first soldier near the safe.
2. The second part of the code is found on the body of the second soldier on the opposite side of the barracks.
3. The last part of the code can be found on the body of the third soldier in the bunker located in the southwest of the area. Players will have to face a Burer to gain access to the code.

Once players have all parts of the code, they can enter it into the safe and unlock it. The code of the Rostok safe is 195726.
