Immersive Fallout Mod
MODA Fallout experience that feels realistic, rewarding, and ultimately much more fun.
Lets assume that in the world of Fallout they use a special light(ish) alloy, but even then it would still set its weight in the range of ~500kg and upwards at the very least.
Any custom/modded weapons will work seamlessly and receive all changes if they happen to use a base aim model.
