CS2 Smoke Lineups Explained

Smoke is the grenade that decides whether a site can be taken at all, and Counter-Strike 2 rewrote how it behaves. Understanding the new model is what separates throwing a smoke from actually taking space with one.

What volumetric smoke actually does

In CS:GO a smoke was a sphere of particles that ignored the world around it. In CS2 it is a volume that fills the space it is in: it pours down stairwells, spreads along a corridor instead of through the wall beside it, stops at a closed door, and leaks through an open window. Two smokes landing a metre apart in an open area look nearly identical; the same two landing near a doorway can produce completely different coverage.

The practical consequence is that where a smoke settles matters far more than it used to, and far more than where it was thrown from. A lineup is valuable because it reproduces a known landing point, not because the arc looks impressive.

Duration and cost

Price: $300
Duration: roughly 18 seconds once fully deployed
Carry limit: one, within the four-grenade total

Eighteen seconds is long enough to cross most spaces and short enough that a smoke thrown too early is worse than no smoke at all — it announces the execute and then evaporates while you are still gathering. Air time is on every lineup page for exactly this reason: a three-second smoke has to leave your hand three seconds before you want cover.

Smoke interacts with everything now

Bullets punch small, briefly-open channels through a smoke. One player spraying into a smoke can see and be seen through the hole they made, for about as long as they keep firing.
An HE grenade blows a large hole in a smoke for a couple of seconds — long enough for a coordinated team to push or pick through. This is a real tactic, not a curiosity, and it is worth learning the HE lineups that pair with your team's smokes.
Fire and smoke cancel: a molotov thrown into a smoke is put out, and a smoke landing on burning ground extinguishes it. Both directions are used deliberately — the smoke that clears a molotov off a plant is often more valuable than one that blocks vision.
Smoke is lit by the environment, so a smoke in a dark area reads differently from the same smoke in the open. It does not change the mechanics, but it changes what you can see silhouetted against it.

Do lineups still work in CS2?

Yes, and they are more valuable than they were. The throw itself is deterministic: the same standing position, the same crosshair alignment and the same movement input produce the same landing point every time. What changed is the payoff — because coverage now depends on exactly where the smoke settles, hitting the intended spot instead of somewhere approximately right is the difference between a one-way and a useless cloud.

What does break lineups is map geometry changing. Valve reworks maps between operations, and a moved crate or a widened doorway invalidates every throw that used it as a landmark. That is why each lineup here records the patch it was tested on and carries verified / broken votes.

Learning smokes in a useful order

Learn the two or three smokes your team's default execute needs on the map you play most. Not the map you find most interesting — the one you actually queue into.
Learn the one-way and the retake smoke for the same site. These are the throws that win rounds you were losing.
Learn a smoke you can throw from spawn. Being able to smoke a mid-crossing before contact is worth more than a perfect site smoke you never get the space to throw.
Only then start collecting. A page of two hundred bookmarked smokes wins nothing; three you can hit while being shot at wins rounds.

One-way smokes

A one-way is a smoke positioned so that a player on one side of it can see through a gap — usually under it, over a box, or through the sliver between the cloud and a wall — while the player on the other side cannot. They exist because the smoke is a volume with edges, and edges can be placed deliberately. They are also the most fragile category of lineup: a one-way depends on the cloud settling to within a few units of a specific place, so the ones that survive are almost always the ones thrown from a fixed lineup rather than by feel.

They are not unbeatable. Anyone who knows a one-way is there can throw their own smoke into the gap, walk a molotov onto the player using it, or simply approach from an angle the gap does not cover. Treat a one-way as a strong opening that gets figured out, not as a position you can sit in all half.

The mistakes that cost the most

Throwing too early. The smoke is on a timer from the moment it lands, not from the moment your team is ready. A smoke thrown as the round starts is usually gone by the time anyone reaches the space it was covering.
Throwing from a slightly wrong spot rather than walking three steps to the right one. Being close is not close enough on a long throw, and a smoke that lands ten units short can leave exactly the gap you were trying to close.
Not calling it. A teammate who does not know a smoke is coming holds their peek through it, gets seen against the edge, and dies to the player you were blocking off.
Smoking your own molotov out. Fire and smoke cancel each other, and a support player throwing a smoke into ground a teammate has just set on fire has spent $700 to achieve nothing.
Learning site smokes and no mid-control smokes. Most rounds are decided before the site, by whoever takes the middle of the map, and the utility for that is what most players never learn.

Smoke in a retake

Attacking utility gets all the attention, but a smoke used defensively — over the bomb during a defuse, or across the angle a post-plant player is holding — is often the higher-value throw. It costs the same $300 and it converts a round that requires winning a duel into a round that requires arriving on time. If a map has a reliable "smoke the bomb" lineup from the common retake approach, learn it before you learn a fourth site execute smoke.
