This article describes a feature in the first Apocalypse Rising

Credits were removed on July 14, 2016.

Credits were a currency in Apocalypse Rising that were used to buy hats and clothing when you first spawned. They were added in the May 30, 2014 update along with hats, and removed in the 2016 Summer Update, when Game Passes were introduced.

The player started with 15 credits when they first started Apocalypse Rising. When those were depleted, the player either had to buy more or be stuck with 0. There was no way to obtain credits other than purchasing them. Credits were needed for certain camo items and hats, such as the Trinity Guard Uniforms and Special Operations Helmet, which could not be obtained in-game.
