When a technician in Stalker 2 is unable to install a specific upgrade, it usually indicates that one or more in-game conditions or requirements have not been met. Understanding these potential blockers is key to resolving the issue.
Potential Reasons for Upgrade Failure
- Incorrect Technician: Not all technicians possess the same skill set or tools. Some may specialize in certain types of equipment (e.g., weapons vs. armor) or only be capable of performing basic to intermediate modifications. Advanced upgrades often require a more skilled or specialized technician.
- Missing Components or Materials: Upgrades typically require specific parts, scrap, or unique items. If these are not present in your inventory, the technician cannot perform the work. The interface should indicate what materials are needed.
- Insufficient Funds: Performing upgrades costs in-game currency. Ensure you have the required amount of Roubles or other relevant currency.
- Prerequisite Upgrades Not Met: Many upgrade paths are tiered. A more advanced upgrade might require one or more basic upgrades to be installed on that specific item first. Check the upgrade tree for dependencies.
- Item Condition: The weapon or armor piece might be too damaged. Technicians often require items to be in good repair before they can be modified. Repair the item first.
- Item Incompatibility: The selected upgrade module may not be compatible with the specific model or type of weapon or armor you are attempting to modify. Not all upgrades fit all gear.
- Technician Lacks Necessary Tools: Some technicians might require specific toolkits (e.g., basic, advanced, expert tools) to perform certain levels of upgrades. They may need you to find these tools for them.
- Story Progression or Quest Lock: Certain advanced upgrades or technician capabilities might only become available after reaching specific points in the main storyline or completing particular side quests.
Troubleshooting and Solutions
- Verify Upgrade Requirements: Carefully examine the upgrade interface. It should detail the cost, necessary components, and any prerequisite upgrades.
- Check Technician's Specialization: If possible, interact with the technician to see if they mention any limitations or specializations. Try visiting a different technician if available, as they may have different skills or toolsets.
- Ensure Item is Repaired: If the item's durability is low, repair it at the technician or using a repair kit before attempting to install upgrades.
- Gather All Required Materials: Double-check your inventory against the list of required components for the upgrade. Acquire any missing items.
- Confirm Sufficient Currency: Make sure you have enough in-game money to cover the cost of the upgrade.
- Follow Upgrade Paths: If it's a tiered upgrade, ensure all preceding upgrades in that path have been installed on the item.
- Locate Toolkits for Technicians: Be on the lookout for toolkits in the game world. Delivering these to technicians can expand their range of available upgrades.
- Progress in the Game: If you suspect a story or quest lock, continue playing through the main campaign or relevant side missions.
- Reload a Previous Save: In rare cases, a temporary game bug might cause an issue. Reloading an earlier save file can sometimes resolve such glitches.
