March 4 CS2 Patch Overhauls Inferno, Tightens Trading Rules, Adds Map Tools

Valve rolled out a targeted Counter‑Strike 2 update on March 4, 2026 that alters Inferno’s A site geometry, tightens inventory and Steam Community Market behavior, and adds developer‑facing scripting and weapon API functions intended to help community map authors and scripters. The public patch notes were reproduced by Hotspawn, Reddit, and Dust2 Us and include verbatim map and scripting entries.

On Inferno the patch notes state plainly: "Balcony at Bombsite A has been extended." and "Graveyard at Bombsite A has been closed to the public." The notes also list a small clipping tweak: "Clipping adjusted at small window next to Second Mid Balcony." Dust2 In added an extra interpretation not present in Valve's lines, saying Valve "reverted the platform to the old railings-style approach like CS:GO." Daniel Morris framed the gameplay impact directly, writing "The changes should make it easier for players to retake the site, a long‑held criticism of the map for many."

Several outlets expanded on the retake angle. Dust2 Us wrote, "The goal of the Inferno update CS2 patch appears to be improving the balance around A site, especially during late round situations." Dust2 In emphasized the defensive relief for CTs, saying "The graveyard position has been closed off giving CTs a massive relief during retakes. The graveyard position allowed players to setup ludicrous crossfires with players on either sides of A-site, mini-pit or even the A-apartments/balcony." Daddyskins added a competitive perspective: "While it might seem minor, these types of changes help keep the map balanced for competitive play."

The patch also changes inventory and in‑game market behavior in explicit terms from Valve's notes: "Starting today, items listed for sale on Steam Community Market will remain in your inventory for use while they are listed (e.g., your weapon can be equipped in your loadout while it is listed). While listed, items cannot be consumed or modified. You can cancel your listings at any time." Valve further added, "Added ability to set your max offer limit for items in the Terminal, and the Arms Dealer will only show offers up to that limit."

For community mappers and scripters the update delivers a long list of function additions and fixes reproduced verbatim in the public notes. New items include: "Added hitEntity to OnBulletImpact event data", "Added Entity.GetAbsAngularVelocity()", "Added Entity.GetLocalAngularVelocity()", and "Added angularVelocity to Entity.Teleport()". Weapon API additions include "Added CSWeaponBase.GetClipAmmo()", "Added CSWeaponBase.SetClipAmmo()", "Added CSWeaponBase.GetReserveAmmo()", "Added CSWeaponBase.SetReserveAmmo()", "Added CSWeaponData.GetMaxClipAmmo()", and "Added CSWeaponData.GetMaxReserveAmmo()". The patch also fixed scripting gaps: "Fixed missing CSPlayerPawn.IsDucking()", "Fixed missing CSPlayerPawn.IsDucked()", "Fixed a bug where JUMP wouldn’t trigger for WasInputJustPressed() and WasInputJustReleased() if the press didn’t cross a tick boundary." and "Fixed a bug where Entity methods GetEyePosition(), GetEyeAngles(), GetHealth(), GetMaxHealth(), and SetMaxHealth() would only work on CSPlayerPawns."

Other mapped items in the patch notes include map updates for community Workshop maps: "Warden: Updated to the latest version from the Community Workshop (Update Notes)" and "Sanctum: Updated to the latest version from the Community Workshop (Update Notes)." Cosmetic and small quality‑of‑life fixes were also listed, including "Fixed a slight tilt in the chicken running animation."

Multiple reproductions of the March 4 notes used ellipses to omit longer sections, so the public excerpts published by Hotspawn, Reddit, and Dust2 Us may not show the full Valve post. The reproduced pages also displayed UI fragments such as "Season4" and "Premier SEASON 4" and editorial strings like "You can find the full patch notes for the new CS2 update here and below:" alongside author attributions including Daniel Morris and site labels such as Dust2 Us. Expect competitive Inferno play and community map scripts to surface practical effects from these changes in the coming weeks as teams and mappers test the altered A site geometry and apply the new API hooks.
