Skins are used to alter the appearance of units, giving them a completely different look on the Battlefield.
Skins can be received from the Cosmetics Wardrobes located in the in-game Shop which are purchased using Eternite. If a player receives a duplicate Skin from a wardrobe, they will be given a small Eternite reward in place of the Skin.
Skins can also be included in Offers, and as rewards from the premium Season Path.
Every unit has multiple skins available. To equip a Skin, tap on the unit you want to customize, and select the 'Skins' section. There, simply tap on the Skin you want the unit to use. The Skin selection applies for the selected Army, if you have multiple Armies, you can use a different Skin for each Army.
