Top flashes: the flashbangs that actually blind you
Prefire ranks your CS2 opponent's flashbang lineups by how many enemies they blinded, and replays how each one is thrown, keys included.

Most players have two or three flashes they throw every half. If you know which one is coming, you turn away. If you don't, you're the one getting blinded.
What it shows
Prefire reads your opponent's last match on the map you're about to play and collects every flashbang they threw. Throws from the same spot that burst in the same place become one lineup.
Then it ranks those lineups by what they actually did: how many enemies they blinded, for how long, and how many kills came from it. Teammates they flashed count against a lineup. Blinds shorter than a second don't count at all, because you can turn away from those.
You get their top three. The lineup they throw most is marked too, even when it isn't one of the best. That's the flash you're most likely to see.
See how it's thrown
Pick a lineup and Prefire replays the throw: from the moment they pulled the flash out to the moment it left their hand.
The path shows whether they were running, walking, crouching or in the air. Below it, the keys light up as they were pressed: W, A, S, D, Shift, Ctrl, Space, and left or right click. Their speed is shown too. A running jump-throw and a crouched right-click lob look nothing alike, and now you can tell which one it is.

How to get the most out of it
- Most used vs most effective. The most used flash is what you'll see first. The most effective one is what gets you killed. Know both.
- Listen for the throw. A jump-throw from the same corner every round has a sound. Once you've seen the replay, that sound is your cue to turn.
- Practise it yourself. Every lineup has a setpos you can copy into an empty server. Throw it a few times and you'll learn exactly where it pops.
- Mind the sample. It's one match, and the count of throws is always shown. Six throws of the same flash is a habit; one throw is a hint.
