Bungie has finally revealed Marathon’s premium currency, called LUX, while promising it can’t be used to buy gameplay advantages.

In a tweet, the official Marathon account reiterated that seasonal gameplay content is free for all players. This includes zones and Runner shells (playable characters) for the extraction shooter.

“There is no pay for power,” Bungie said. Premium Pass rewards only include cosmetics, not gameplay items. And LUX can only be used for cosmetics, “not gameplay advantages.”

Meanwhile, Reward Passes do not expire, so you can buy a previous season’s Reward Passes. You unlock rewards in your Rewards Passes using Silk, which is earned by playing the game. You can’t buy SILK. You can also earn cosmetics via the Codex, with others available for purchase.

Confirmation of Marathon’s premium currency comes just hours before the game itself goes live (check out the Marathon release times here).

We’ve got plenty more on Marathon, including one Bungie developer’s commitment to “fontslop,” and Bungie’s words of reassurance on Marathon’s difficulty curve. Check out IGN’s Marathon review so far to find out what we think.
