Maya customization
A total of 23 Heads and 93 Skins can be unlocked for Maya. The non-default heads and skins can be unlocked through random enemy drops, specific (though rare) enemy drops, quest rewards, challenge rewards, downloadable content and in-game trading with other players.

DLC Heads
Paid DLC skins and heads are unlocked in the customization menu directly. As a result, they are account-bound and cannot be traded. The special edition head comes as a single inventory item, which can be traded.
