I wanted to ask how you can get this golden camouflage in Fortnite that the weapons are also gold for opponents
Only the lvl 100 skin or the other agents can do that if you are some really high level or something
You have to earn these camouflages with level. That means for each level your Midas skin becomes more gold after level 100, for example. The highest level you have to reach to have all skins on gold is 300.
You don't need camouflage to gild weapons and vehicles. For this you need the lv. 100 skin midas. As soon as you hold a weapon in your hand with Midas, it becomes gold and as soon as you step into a vehicle it is also gold-plated. This works with the standard Midas once you have unlocked it (alsi already from lv. 100). Sometimes it bugs around and you have to get in and out of the vehicle or throw the weapons out of the inventory and pick them up again.
