The golden weapons are the only clone weapons to be designed very well. Its not a simple recolor like those awful neon weapons. The base texture was remade (as in no sign of damage, scratches to the gun), designs were more though out and they added a new layer to make them SHINE! Their HUD icons are even made yellow instead of the traditional red.
Id recommend buying these. There is no need to be butthurt just because "they are reskins", these are optional and profit of these DLCs help fund KF2. The only reason to complain is if the reskin was lacking in quality, which these beauties definitely are not lacking.
