Top HEs: where their grenades land, and what they cost you
Prefire shows your CS2 opponent's three most damaging HE grenade lineups, the damage each one did, and replays exactly how they threw it.

An HE grenade rarely kills on its own. It takes 30 to 60 HP off whoever is holding the spot it was aimed at, and the next duel is decided before it starts.
What it shows
Prefire reads your opponent's last match on the map you're about to play and collects every HE grenade they threw. Throws from the same spot that burst in the same place become one lineup.
Each lineup is ranked by the damage it did to enemies. You get their top three, each with how many times it was thrown, how much it did per throw, how many players it hit, and the round of its best throw. On the map, you see the flight, the burst, and exactly how much each enemy lost.
See how it's thrown
Like the flashes, every HE lineup comes with its throw replayed. You see where they pulled the grenade out, how they moved, which keys they held, and when they let go. Seven throws of the same lineup, thrown the same way every time, is a routine, and routines can be read.

How to get the most out of it
- Look at the rounds. An HE thrown the same way in rounds 3, 9 and 20 is a habit, not an accident. Expect it again.
- Don't stand where it lands. If you know where their HE goes, hold that angle from a step back, or hold it with full HP and a teammate ready to trade.
- Put it next to Positions. The burst usually sits on a spot the heatmap shows the enemy team holding. Together they tell you what they're clearing before they walk in.
- Steal it. Copy the setpos into an empty server and learn the lineup yourself. A nade that works in their games works in yours.
