Guns are an integral part of the Wild Hunt game.
There are many available variations with certain strengths and weaknesses and different statistics.
Better guns inflict more extra damage and have better clip capacity which allows players to shoot more.
In gear panel you can upgrade every owned weapon and its parts, just simply click/tap arrows to find the desired weapon. On the right side, there is a window which shows all weapon parts.
After clicking/tapping a weapon part, a panel will appear (on the left side) containing information about all changes in statistics caused by an upgrade.
