What is the active CS2 map pool?
The active duty pool is the canonical Valve-selected set of maps used in tournament CS2. At any given time, 7 of the 9+ playable maps are "active" (playable at Tier-1 events) and the remaining sit in reserve. The current rotation usually includes some mix of Mirage, Inferno, Dust2, Nuke, Ancient, Anubis, Train, Overpass and Vertigo. Pool changes matter enormously — a team whose map pool overlapped an outgoing map loses ~14% of their practice time overnight, and teams that spent the previous cycle mastering a newly-added map vault up the rankings. Our maps hub tracks the current pool.
