I remember the moment I hit the extraction timer with a backpack full of skins and a balance that looked too thin. My pulse climbed faster than my loadout value as the extraction window closed. You, reading this, probably want to stop gutting your Credits for one flashy helmet and keep more LUX for when it counts.
I’ve spent hours trading off shiny cosmetics and core upgrades across Bungie’s ecosystems and other shooters, so I’ll tell you what matters here: which currency buys flash, which buys function, and where you can be economical without feeling stingy.
A friend at my desk once sorted their receipts into three piles — cash, cards, and gift vouchers. From that small habit: the shape of Marathon’s economy becomes obvious.
Marathon ships with three primary currencies. Each one has a job: one pays for cosmetic options, one buys weapons and upgrades, and one is the seasonal progression token. Treat them differently and you keep more of what you want.

I watched someone buy a single shader with a small stack of LUX and regret it five minutes later. The fallout taught me to treat this currency differently.
LUX is the premium currency in Marathon. It’s purchased with real money and handles the game’s cosmetic and premium storefront items in much the same way Silver does in Destiny 2. Think of LUX as the VIP pass to Marathon’s cosmetic boutique.
Pricing at launch in the US looks like this (rounded EUR shown):
- 500 LUX: $4.99 (€5)
- 1,100 LUX (1,000 + 100 bonus): $9.99 (€10)
- 2,250 LUX (2,000 + 250 bonus): $19.99 (€20)
- 3,950 LUX (3,500 + 450 bonus): $34.99 (€35)
- 5,750 LUX (5,000 + 750 bonus): $49.99 (€50)
- 12,000 LUX (10,000 + 2,000 bonus): $99.99 (€100)
What is LUX in Marathon?
LUX buys cosmetics, select premium bundles, and some convenience items in the Armory and storefronts tied to Bungie’s launch plans. It’s intentional: you won’t use LUX for the core weapon economy. Bungie keeps LUX separate to let players choose whether they want to spend real money for looks and seasonal content.
Can I transfer LUX between platforms?
No. LUX is platform-bound. If you buy LUX on one platform — Steam, Epic, PlayStation, or Xbox — it stays on that platform. If you play Marathon on multiple platforms, budget accordingly and avoid impulse purchases that leave you short in the account you actually play on.
How do I buy or earn LUX?
Primary method: direct purchase through the platform store (Steam wallet, PlayStation Store, Xbox, Epic). There are occasionally promotional bundles or bonus LUX bundles around seasonal drops, similar to bonus structures Bungie has used for Destiny 2. Earning LUX for free is rare; expect most LUX to come from paid transactions or promotional events.
At a flea market I once watched a trader haggle until the money on the table smelled like victory. Credits in Marathon act the same way at the Armory.
Credits are the common in-game cash. You buy weapons, armor pieces, mods, and Faction upgrades with Credits. Random loot you keep or extract is often auto-sold for Credits, and you can sell nearly any gear back for currency. Credits are the lifeblood of your Arsenal.

Play runs, extract successfully, sell what you don’t need, and harvest Credits that way. Also budget some for Faction skills and upgrades — they’re purchased directly with Credits and will affect how you perform on future runs.
I pulled up a seasonal reward screen and felt like a collector opening a postcard pack. That feeling is what Silk is built to create.
Silk is the seasonal progression currency used with the Reward Pass. As you level the season pass, you earn Silk and spend it inside that pass to claim items on the progression track. You gain Silk primarily by playing through season objectives and leveling the Reward Pass.
Tips I give players: decide whether you’re chasing cosmetics in the store (LUX) or steady progression and seasonal gear (Silk), and then allocate time and spending accordingly. Use the Armory and community tools — the Bungie forums, subreddit communities, and third-party stat trackers — to keep an eye on what’s worth spending Credits or Silk on versus saving for LUX-only drops.
If you could change one thing about how Marathon handles currency, what would you push Bungie to do differently?
