From the launch of the Epic Loot expansion, the economy of Robocraft has transitioned away from having the real money currency Galaxy Cash in-game. From today all in-game real money purchases are now represented by their localised monetary value provided by our third party payment vendor, Xsolla. This is all so players can keep track of how much they are spending in game without any additional calculations.
To view your new Xsolla balance you simply need to click either "Add premium" or "Add crates". This should then open a new window, either in your Steam Overlay or a ingame browser.
Your balance will be shown in the top right of this window.
