Fallout 4: Vault-Tec – All Experiment Rewards & Results

The Vault-Tec Workshop add-on for Fallout 4 includes several settlement-boosting experimental prototypes your Sole Survivor can tinker with.

These four unique machines can make your settlers happier, provide cash bonuses, or even kill dwellers if you select certain variations. The in-game notes are extremely vague, only hinting at the actual results of these experiments. If you’re sick of guessing and want to know exactly how experiments provide benefits (or don’t), check out the full list of rewards and results below.
