What the CS2 August 4 Cache update actually means for competitive play
Valve's August 4 patch removed the Outside A boost spot, fixed grenade geometry, and shipped a massive scripting toolkit. We break down which pro teams were using the boost and what the new bomb-event hooks mean for the workshop community.
Valve dropped the August 4 CS2 update overnight, and while the patch is officially a "no weapon balance changes" release, it has real competitive implications. The biggest one: the Outside A boost spot on Cache is gone.
What the patch actually contains
- Grenade geometry fix — grenades can no longer pass
through level geometry in certain edge cases. Affects Cache most visibly, but applies globally.
- Cache polish — gaps, collision spots, flickering
assets, and the Outside A boost spot removed.
- Shelter updated to the latest Community Workshop
version.
- Massive scripting toolkit expansion — new Instance
events (OnWeaponPickup, OnBombExplode, OnGrenadeBounce), new CSPlantedC4 methods (IsBombsiteA, IsBombsiteB, GetPlanter, GetDefuser, IsActive, IsExploded, IsDefused, GetPlantTime, GetExplodeTime), CSGrenadeProjectileBase API surface, and CSPlayerPawn.HasDefuser/SetHasDefuser.
The patch is ~845 MB and no weapon balance changes.
Why the Outside A boost removal matters
Cache returned to CS2 in late April after seven years out of the active pool, and entered the Active Duty map group on July 9 for Premier Season 5 (replacing Overpass). In pro play, the Outside A boost spot became one of the most-discussed utility positions — Ts could pick up an unexpected angle on a CT rotating from A site, and several teams built default executes around it.
With the spot gone, those executes are dead. Expect:
- More AWP holds from the standard Outside A angle
(now that the off-angle doesn't exist, the meta AWPer is uncontested).
- Slower A executes — without the boost, Ts have to
use util to take space on Outside A the conventional way.
- CT-side buff on Cache — the boost was the main way
Ts broke the otherwise-strong CT setups on A site.
Pro teams will adapt within a week. For ranked Premier players at lower ranks, the change is invisible — most people in Silver–Gold weren't running the boost anyway.
The scripting changes are the bigger story
The Instance event additions are huge for the workshop community. The new hooks mean custom game modes can now react to bomb plant events, bomb defuse attempts, weapon pickups, and individual grenade bounces with direction vectors. Workshop map authors have been asking for CSPlantedC4 state methods since 2024; this release effectively lets them build full retake servers and bomb-event minigames in the same way Minecraft command blocks work.
Notable things the new API enables:
- Custom bomb-timer modes with different win
conditions (e.g. "defuse with 1 HP left").
- Retake servers with full bomb-state awareness —
custom logic can grant defuse kits to the defuser based on plant-time, or restrict mid-plant rotation.
- Anti-cheat workshop plugins that detect impossible
grenade bounces.
- Trailing-effects mods that draw lines on every
grenade bounce using the new normal vector.
Expect at least 3–5 marquee workshop projects shipping within the next 2 weeks.
What's next for Cache
Valve has said Cache will continue receiving polish passes. The current open betas for the Active Duty group rotate every 6 weeks, so Cache is locked in until at least mid-September. After that, the next map rotation is likely.
FAQ
Will the Cache boost removal affect my Premier rank games?
If you're below Master rank, no — the boost spot was a pro-level utility. Most ranked games at Silver–Diamond never involved the boost. If you play in Master+ or Faceit level 8+, you'll feel it in the first week as the meta reflows around the missing off-angle.
Are grenades completely fixed now?
No. The August 4 patch fixed a specific case where grenades could pass through level geometry — primarily Cache. There are still known edge cases on other maps (Mirage has a smoke that occasionally clips through window frames; Ancient has a flash bug at top-mid). Expect incremental fixes over the next 2–3 patches.
When is the next Cache update?
Valve hasn't committed to a timeline, but Cache polish shipped in 3 of the last 4 monthly patches. Expect another small polish update in the first half of September, and a larger mid-season update around October. Cache is locked in the Active Duty group until mid-September at the earliest.
Can I host my own workshop mod with these new hooks?
Yes, if you're already familiar with the CS2 workshop scripting system. The new hooks add bomb-state and grenade-bounce APIs — Valve has confirmed they work in both community servers and verified official workshop uploads. You'll need to update your CS2 client to the August 4 build to use them.
