[01]/Pass mechanic
How the Armory Pass works.
The flow is straightforward. You buy the pass from inside the game at the price Valve sets for the current season. The pass attaches to a single Steam account and stays active for the duration of the season, which runs for the length of one CS2 content cycle, typically months rather than weeks. Once the pass is active, every match you play earns XP under the standard CS2 XP rules. That XP feeds two things at once: your normal profile rank progression, and the pass track. As the pass track fills, you cross pass levels, and each level converts a chunk of XP into stars on a defined curve. Early levels are cheap in XP; later levels cost more XP per star, which is the seasonal mechanic that rewards consistent play over a brief sprint. Stars accumulate in your armory wallet and stay there until you spend them. Spending happens in a separate in-game catalog screen, where each item is listed with a star price. The catalog itself rotates: a subset of items is available at any given time, and Valve refreshes that subset partway through the season so the late-season catalog is not the same as the launch-day catalog. When the season ends, unspent stars are forfeited and the next season's pass starts from zero.
