Smoke mechanics in CS2: what changed from CS:GO
How volumetric smokes work in CS2: filling space, clearing smoke with HE and bullets, extinguishing fire and how to use it.
In CS2 smoke is volumetric: it fills rooms, flows around obstacles and reacts to shots and explosions. This changes tactics.
📌 How smoke behaves
Smoke spreads through space: in a narrow corridor it stretches along it, in a room it fills it.
It flows through doorways and under arches instead of stopping as a neat sphere.
💥 Clearing smoke
An HE grenade briefly pushes smoke aside and opens a gap.
Bullets punch temporary holes in smoke you can see through.
After a few seconds the smoke closes the gap again.
🔥 Smoke and fire
A smoke thrown into a molotov or incendiary puts out the fire.
A molotov thrown into an existing smoke does not ignite.
🎯 How to use it
With an HE: throw an HE into the smoke and walk through the gap right away.
Against someone clearing it: hold the angle where an enemy might clear the smoke and push.
Extinguishing fire: keep a smoke for retakes to put out a molotov on site.
⚠️ Tip
Do not stay inside smoke for long while enemies are spraying it — even random shots open holes and can hit you.
