Most costumes are acquired through premium currency (gems) is currently one of the ways Trendy Entertainment hopes to make money through DD2 which is a Free-to-Play game. As such in order to avoid a pay-to-win scenario, costumes are only cosmetic, affecting animations and graphics but not providing stat benefits.
* There are certain costumes that are obtainable without using premium currency. Those are only through Defender Pack (which will have a certain chance to drop in Onslaught or acquired through premium currency) and . However, there are 2 that can only be acquired through obtaining codes by social media (liking DD2's Facebook Page and following DD2's Twitter page).
* And there are certain costumes which is alternatively available through certain DLCs too.
