State of Decay How to Repair Weapons and Find a Tools Expert
First you need to build a basic workshop (5 Construction Materials and 10 Influence). It takes 15 minutes to get built. During this time you can already go to work on finding a tools expert.
During “Stranger in Trouble” Missions you can find all kinds of experts to join your group. It shouldn’t take too long until you come across a tools expert. Use your Radio Room and get new survivor locations for 100 Influence.
After you rescued the tools expert and brought him home safely, your weapons will be automatically repaired after they have been stored in the supply locker for 1 in-game day.
