Recovering the lost arts and science of the old world can be a difficult task all on your own - but luckily, we have documented knowledge sources to help us. Research materials are required to uncover some of the advanced research in the game. In Judgment they are an item that Survivors can obtain in combat missions and use for research.
- Research materials are rare. Scavenge more locations to gain more.
- They are far more common in ruined cities, be sure to venture out and look for them beyond your borders. (Maybe in that old school!)
