To prefire is to start shooting at a spot as soon as it comes into view, before you confirm an enemy is there. Done well, it wins fights that a normal reaction would lose. Done badly, it wastes bullets and tells everyone where you are. This guide explains when to prefire in CS2 and how to choose angles worth the risk.
Why does prefiring work?
When you clear an angle, the defender is usually already aimed at it. You have to see them, react and shoot. If you know a spot is commonly held, you can skip the reaction. Your crosshair arrives on the spot already firing.
This is most useful at close range. At long range, the defender has more time and you have less certainty.
Which angles are worth a prefire?
Good prefire spots share a few traits:
- Common: defenders use the spot often enough that the bet pays off.
- Close: you clear it at short range, where one burst decides the fight.
- Predictable head height: the defender is standing or crouching in a known way.
- Tight: the spot only comes into view for a short moment.
Think of corners next to a site entrance, small boxes on a site and short connectors. Exactly which spots are common changes with each map and with how teams play. Learn them on the maps you play using our callout guides, such as Mirage callouts and Inferno callouts.
When not to prefire
Prefiring has costs. Avoid it when:
- The spot is rarely used: you waste bullets and may need to reload in the next fight.
- Stealth matters: shooting gives away your position and your timing.
- You have little ammo: pistols and SMGs run out quickly.
- Teammates might be there: late-round confusion can cost a teammate's health.
Prefiring is also different from shooting through walls. Wallbanging aims at enemies behind cover. Prefiring aims at a spot that is about to become visible. Our wallbang guide covers the other case.
How to prefire well
Stop before you shoot
A prefire while running is a wasted spray. Come to a stop as the angle opens, then shoot. The counter-strafing guide explains the timing.
Aim at head height
Place your crosshair at the head height of a standing or crouching defender before the angle opens. The crosshair placement guide helps here.
Use short bursts
Fire a short burst, not a full spray. If nobody is there, stop shooting, check the next angle and keep your magazine for the real fight.
Pair it with utility
A flash can push a defender out of their spot or blind them while you clear. A pop flash followed by a prefire is a strong combination when the timing works.
How to practise prefiring
The fastest way to learn spots is with Workshop practice maps that place bots on common angles. Our guide to CS2 prefire maps covers how to use them. These maps teach you where defenders often stand and train you to stop and shoot quickly.
You can also walk through a map in an offline game and clear each spot slowly. Say out loud whether you would prefire it or not, and why. This builds decision-making, not just muscle memory.
Common prefire mistakes
- Spraying every corner: by the time a real enemy appears, you are reloading.
- Prefiring too early: bullets hit the wall before the spot is in view.
- Prefiring too low: body shots at close range give the defender time to answer.
- Forgetting the next angle: after a prefire, your crosshair should move to the next likely spot straight away.
Review a few of your own entries in a demo. Count how often you fired at empty spots and how often a prefire actually won the fight. That ratio tells you whether you prefire too much or too little.
Quick decision guide
| Situation | Prefire? |
|---|---|
| Close, common site corner during an execute | Usually yes |
| Long-range angle with no info | Usually no |
| Silent lurk behind enemy lines | No |
| Low ammo after a fight | Reload first if safe |
| Spot an enemy was just heard at | Often yes |

Frequently asked questions
What does prefire mean in CS2?
It means shooting at a commonly held spot as it comes into view, before you actually see an enemy there.
Is prefiring a waste of ammo?
It can be if you do it on unlikely spots. Use short bursts on close, common angles and stop firing if nobody is there.
How do I learn prefire spots?
Use Workshop prefire practice maps and slow walk-throughs of your main maps, combined with reviewing where defenders killed you in demos.
