CS2 active duty map pool: the seven maps, the Cache swap, and how Premier picks your map
The active duty pool is the seven maps Counter-Strike 2 uses for Premier and for every Major.[3] Valve changed it once in 2026 when Cache replaced Overpass, then changed how a Premier lobby decides which of those seven you actually play.[1][2]
Both changes are live now, and a lot of older map guides still list the wrong pool.
The seven maps
Ancient, Anubis, Cache, Dust II, Inferno, Mirage and Nuke, which Liquipedia's map portal lists under Active Duty and Dot Esports' pool page names as the current seven.[3][4]
Ancient
Three lanes and a heavy fight for early control at the chokepoints.[4] It joined the pool in 2021 and has stayed through every swap since, which makes it one of the safer maps to learn if you want a pick that will still be there next season.[4]
Anubis
The only active duty map Valve did not build itself.[4] Dot Esports describes it as leaning further toward the Terrorist side than anything else in the pool, and as a map that rewards teams with raw firepower.[4] It came back in January 2026 for Premier Season 4, replacing Train.[4]
Cache
Cache returned twice. Valve's April 2026 post announced it was back in the game,[5] and the Season 5 post on 8 July 2026 put it into active duty: "Cache has officially arrived, and replaces Overpass in the active duty map pool."[1]
It is a mid-control map, closer in rhythm to Ancient than to Dust II.[4]
Dust II
In the pool since April 2024, when it took Overpass' place.[4][3] Long sightlines, double AWP setups on the CT side, and still the map most players learn first.[4]
Inferno
Banana and the A pit. Inferno has been a fixture since 2017 and asks more of your utility than any other map in the pool.[4]
Mirage
The most played map in the pool and the one with the most guides written about it.[4] Dot Esports calls it the best map to learn first, pointing at its pick rate, the volume of community material and a layout that teaches mid control, smoke executes and trading.[4]
Nuke
The vertical map, with the two bombsites stacked on top of each other.[4] Volumetric smokes in CS2 added smoke-pop plays in yard, and the layout itself has been stable since 2017.[4]
What left the pool
Overpass. Valve moved it out when Season 5 started on 8 July 2026, and it now sits in the reserve pool alongside Train and Vertigo.[1][3]
Reserve maps stay playable in Competitive, Casual and Deathmatch, they are just not in Premier. Train left active duty in January 2026 when Anubis came back.[1][4]
Office and Italy are the hostage rescue maps and were never part of the pool.[3]
Community maps added in the same update
Valve's Season 5 post also added Boulder, Fachwerk and Shelter to Competitive, Casual and Deathmatch, and put Debris and El Dorado into Wingman.[1] None of those are active duty maps and none of them appear in Premier.[1]
How Premier picks the map now
This is the change that catches people out. Until September a Premier lobby banned maps until one was left.[2]
Valve's Rush Hour update on 22 September 2026 replaced that process: "instead of banning down to a single map, teams will vote to pick two maps each. After all four maps are picked, a single map will be randomly selected and the match will begin."[2]
Valve's stated reason is that a team which spends time developing strategies on a map should get a chance to benefit from that investment.[2]
Three consequences follow. Four maps is the new minimum, because half the picks in any lobby come from the other team. Veto practice built around bans is worth less than it was. And the post does not say what order the picks happen in or whether both teams can pick the same map, so any guide claiming to know either detail is guessing.[2]
What to practise
If you play Premier, pick four maps and learn them properly: the two you would always choose, plus the two every lobby is likely to pick. Mirage is the only map that has stayed in the pool across CS:GO and CS2, and Inferno has been there since 2017, so both are reasonable anchors for a small map pool.[4]
FAQ
What maps are in the CS2 active duty pool right now?
Ancient, Anubis, Cache, Dust II, Inferno, Mirage and Nuke.[3][4]
When did Cache come back?
Valve shipped its return on 28 April 2026,[5] and moved it into active duty on 8 July 2026 with Premier Season 5.[1]
Is Overpass still in CS2?
Yes. It left active duty, so it is not played in Premier this season, but it remains in the reserve pool and is playable in Competitive, Casual and Deathmatch.[1][3]
Is Train in the active duty pool?
No. Anubis replaced Train in January 2026, and Train is a reserve map.[4][3]
How does Premier choose the map now?
Each team votes to pick two maps, and one of the four picks is drawn at random.[2]
Which map should I learn first?
Mirage. Highest pick rate, most community resources, and a layout that teaches the parts of the game that transfer to everything else.[4]
Do Majors use the same maps?
Yes. Majors use the active duty pool, and teams veto during the pick-ban phase to decide the maps in each series.[4]
