The weapons in Back 4 Blood are designed with a realistic and high-detail art style, featuring a mix of modern firearms and makeshift melee weapons. Each weapon showcases distinct textures such as scratched metal, worn wood grips, and matte finishes, with some displaying battle-damaged effects like dents and rust. Firearms include detailed mechanical parts like bolts, magazines, and scopes, while melee weapons often have organic shapes with sharp, angular edges for combat efficiency.
