CS2 Maps: how the active pool officially changes
Contents
This piece draws on Valve’s official news post Season 5, Armory, and More and the maps section of the Meet CS2 page.
What the active pool is
The active duty map pool is the official set of maps used for matches in the main competitive modes, Premier among them. It’s not the full list of maps available in the game overall, but a narrower, Valve-curated selection that changes periodically.
We cover how match results on these maps affect a player’s personal rating in our piece on Premier and CS Rating.
The latest confirmed pool change
The most recent officially recorded fact: on 8 July 2026, the map Cache replaced Overpass in the active duty map pool. This is confirmed directly by the official news post on counter-strike.net, not by third-party sources.
That same news post records broader map changes outside the active pool:
- Boulder, Fachwerk, and Shelter were added to the Competitive, Casual, and Deathmatch modes.
- Debris and El Dorado were added to Wingman.
This shows that Valve’s map work happens on two levels at once: a narrow competitive active pool, and a broader set of maps for everyday modes.
Three map-rework categories
The Meet CS2 page describes the system Valve uses to classify map updates during the move to the Source 2 engine. There are three categories:
- Full Overhaul — a complete rebuild of the map from scratch. The official example is Overpass.
- Upgrade — the map keeps its layout but gets new Source 2 lighting and materials. The official example is Nuke.
- Touchstone — minimal changes: lighting and character-silhouette readability get updated, while the rest of the map stays essentially unchanged. The official example is Dust II.
This classification explains why some classic CS:GO maps look almost unrecognizable in CS2 while others look almost the same as they did years ago: it’s a deliberate division of labor, not an inconsistency.
Community maps and the Workshop
The active pool is an official, Valve-curated list. Running alongside it is a much wider body of community maps available through the Steam Workshop, where authors publish their own projects, and the best of them can eventually make it into the active pool or one of the modes. More on how this works technically in our piece on Steam Workshop in CS2.
What is officially NOT stated
- A full, current list of maps in the active pool. Official sources record individual changes (replacements, additions) rather than publishing a single exhaustive list as of a specific date in one place.
- How often the pool is updated. There’s no confirmed official schedule — “once a season” or any other cycle.
- A complete list of maps in each of the three rework categories. Only one example per category is named (Overpass, Nuke, Dust II), not a full list.
- The criteria Valve uses to decide which map to replace and which to keep. The reason for swapping Overpass for Cache is not officially explained — only the fact of the swap itself.

Technically, the map updates are part of the wider move to Source 2, which touched not just maps but lighting, smoke physics, and the interface too. For the full scope of those changes, see our piece on the transition from CS:GO to CS2.
Frequently asked questions
Which map was most recently replaced in CS2's active pool?
Per official Valve news, on 8 July 2026 the map Cache replaced Overpass in the active duty map pool. This is a confirmed fact from the official news page on counter-strike.net.
How many map-rework categories does Valve define?
Three: Full Overhaul (a complete rebuild of the map from scratch), Upgrade (new Source 2 lighting and materials without changing the layout), and Touchstone (minimal changes to lighting and readability while the rest of the map stays as it was).
Which maps belong to each rework category?
The officially named examples are: Overpass for Full Overhaul, Nuke for Upgrade, and Dust II for Touchstone. A complete list of maps in each category is not given on the pages we checked.

Yes, through the Steam Workshop. The active pool only concerns official competitive modes like Premier, while community maps run separately from it.

The confirmed sources show that changes do happen, but there's no officially stated fixed update schedule (such as 'once per season') on the pages we checked.
