Counter-Strike 2 July 2026 update — Cache returns to Active Duty, Premier Season 5, C4 explosion rework

Counter-Strike 2 July 2026 update — Cache returns, Premier S5, C4 rework

CS2's July 8, 2026 update is one of the most substantial mid-year patches of 2026. The update adds Cache to the Active Duty Map Pool (over Overpass), launches Premier Season 5, and applies a comprehensive C4 explosion rework that changes the post-plant meta. The patch also includes 2 new weapon collections (Spy Tech + Arabesque), 2 new sticker collections, and a Source 2 engine update that improves performance on mid-range hardware.

The update is the lead-in to the Cologne 2026 Major (which concluded in early July) and the post-Major competitive reset. The full patch notes are detailed below.

Map pool changes

Cache returns to the Active Duty Map Pool for the first time since CS:GO 2017. Cache was one of the most popular CS:GO maps and has been a community-requested return for years. The return is a community-favorite addition that gives the Active Duty pool 8 maps (Mirage, Inferno, Dust II, Nuke, Ancient, Anubis, Vertigo, Cache).

Overpass is removed from the Active Duty pool. Overpass was added to Active Duty in 2024 but never achieved the popularity of the other 7 maps. The removal frees up a slot for Cache and rotates Overpass to the "Reserve" pool (available in matchmaking but not in competitive).

Other map changes:

• Boulder, Fachwerk, and Shelter added to Competitive, Casual, and Deathmatch
• Debris and El Dorado added to Wingman
• Arden, Hold, and Edum removed from all game modes (community maps that didn't reach active play)
• Dust II — fixed the pixel gap outside the tunnel and adjusted clipping
• Inferno — fixed clipping at the top of Mid (prevented pixel boosting)
• Cache — various clipping adjustments

Premier Season 5

Premier Season 5 launched with the patch. The new season introduces:

• Updated map veto format for Premier matches. The new format is a "Veto + Ban" hybrid: each team bans 1 map, then picks 1 map from the remaining 6, then the unused map is the decider. This is faster than the old "Ban 4, Pick 1, Decider 1" format.
• New ranking distribution. Premier S5 introduces the "Top 500" leaderboard (was previously Top 1000). The change makes the top leaderboard more competitive.
• Cologne 2026 Major Champions badge — players who correctly predicted the Major winner receive a permanent profile badge.
• New Premier rewards — Premier S5 features a "CS:GO Legacy" reward set, including a CS:20 case, a 5-year veteran coin, and a souvenir package.

C4 explosion rework

The C4 explosion model has been reworked across all official defusal-mode maps. The changes are technical but gameplay-impactful:

• Damage is now calculated based on precomputed simulation values integrated into the compiled map. This means C4 damage is now 100% consistent across all maps and all servers. Previously, the damage calculation used a server-side physics simulation that could produce 1-2 frame variations.
• The shockwave from explosions now expands rapidly from the center rather than being applied instantaneously. The new shockwave has a 0.4 second "expansion" period (was 0.0s). The new model is more realistic and gives defenders a 0.4 second window to escape the blast if they're not in the direct line of sight of the bomb.
• The "plant for default" meta is buffed. The new explosion model rewards T-side players who plant the bomb in the "default" position (the most protected position on the map). The buff is intentional — Valve has signaled they want to encourage more strategic post-plant play.

The C4 rework is the most significant gameplay change of the patch. The new model rewards better post-plant positioning and punishes defenders who peek too aggressively.

New weapon and sticker collections

The update adds 2 new weapon collections and 2 new sticker collections:

Weapon collections:

• Spy Tech — 18 skins themed around spy/espionage (e.g., silenced weapons, hidden blades, disguise gear). The collection is the first "theme" collection since The Huntsman Collection (2021).
• Arabesque — 18 skins themed around Middle Eastern/Arabic art. The collection is the first "regional" collection since The St. Marc Collection (2015).

Sticker collections:

• Fruits & Vegetables — 24 fruit and vegetable-themed stickers. The collection is the first "everyday object" sticker collection since the Bathroom Series (2016).
• Auto Racing — 24 racing-themed stickers. The collection is the first "motorsport" sticker collection since the racing collab with Formula 1 (2019).

The Train 2025 and Sport & Field weapon collections, along with the Sugarface 2 and Elemental Craft sticker collections, are no longer available.

Cologne 2026 Major shop

The Cologne 2026 Major Shop is live. The shop includes:

• Cologne 2026 stickers (gold, holographic, glitter, paper, signature)
• Cologne 2026 player autograph capsules (one per team, 12 teams)
• Cologne 2026 Souvenir Packages (gold + player signature, with random Major map skin)
• Cologne 2026 Pick'Em Challenge (predict the bracket, win a free skin)

The shop also adds the "Lowest and highest sticker price in the last 7 days" display to the Cologne 2026 Major Shop. The new tool helps buyers track sticker price trends before making a purchase.

Workshop + scripting improvements

The Workshop update includes significant new functionality for map makers and mod authors:

• Instance.QueueAfterThinks — schedules a function to run after a queue of "think" events. Useful for chaining scripted events.
• Instance.OnWeaponDrop — fires when a player drops a weapon. Useful for kill-feed events and custom game modes.
• CSWeaponBase.GetOriginalOwner — returns the original owner of a weapon (useful for kill-confirm game modes).
• Custom Paint Job Extended — now supports overlay mask texture and unique overlay UV randomization. The new feature is a major upgrade to the skin creator tool.
• Script compilation errors now display file name and line number. The previous "generic" error messages made debugging painful.
• Support for deprecated vts assets has been removed. Map makers who haven't migrated from vts to vtfs will see compile errors.

The Workshop update is a "quiet win" for the community. The new features are highly requested by map makers and the compile-error fix alone will save hours of debugging.

Engine update

The Source 2 engine has been updated to the latest version. The update includes:

• Reduced scoreboard rendering cost — the scoreboard now uses 30% less GPU time. The improvement is most noticeable on low-end hardware.
• Fixed material blending effects vanishing when players approach closely — the bug affected several maps (Inferno's Banana area in particular, where the dirt on barrels would vanish when players got close).
• Enhanced sticker rotation precision — stickers can now be rotated in half-degree increments. The new precision is a small but welcome improvement for skin creators.
• Various Source 2 bug fixes — 12 minor bug fixes not detailed in the patch notes.
