Crafting 
Compound V
Compound V is the permanent way to gain superpowers. You'll need to craft a syringe first using basic materials, then fill it with the serum recipe. Check your crafting table for the syringe recipe—it requires simple resources you can gather early.
Once you have an 
empty syringe, craft Compound V using the full recipe. This creates a filled syringe ready for injection.
Injecting the Serum
1. Hold the filled Compound V syringe in your main hand
2. Look at your character (first-person view is fine)
3. Hold down Right Mouse Button (RMB) until the injection completes
4.
You'll receive one random superpower permanently. Powers include Heat Vision, lightning control, blood manipulation, levitation, and flight. If you're unhappy with your power, you can inject again—but each injection overwrites your previous ability.
Testing Your Power
Once injected, try using your new ability in combat or exploration. Different powers have different activation methods—some are passive, others require aiming or holding keys. Experiment to learn your power's mechanics.
