Stalker 2: Heart of Chornobyl has a huge map with several locations that are locked off, requiring players to either find a code or a key to access them.

One of these locations is called the Agricultural Workshop in the Yantar region, with a locked stairwell that leads to some valuable loot. Here's how players can unlock access to upper floors and secure the loot.
