- Check the final price. Compare both stores’ current totals, including any applicable taxes or fees shown at checkout. A sale price can expire or change.
- Verify region and seller terms. Green Man Gaming’s page stated no regional restrictions when checked, but review the current product details and terms before purchase.

Platforms and cross-save
Bungie lists Marathon for PC, PlayStation 5, and Xbox Series X|S, and says the game supports cross-play and cross-save. Bungie’s release announcement explains that cross-save requires a compatible copy on each system used; other platform versions are sold separately. A PC key therefore does not, by itself, provide a copy for a console.
