Long A on Dust2 has been discussed for twenty years, but most analyses treat it as a straight line. In reality, the same flashbang behaves drastically differently at the entrance and the corner due to the terrain's three distinct slopes. This article breaks down how each segment rewrites the duel economy.
Short Intro
Dust2's Long A has been talked about for two decades, but most discussions treat it as a straight line: who peeks first, who shoots first, who flashes first. In actual play, you'll find that the same player with the same flashbang gets wildly different results at the entrance and at the corner. The reason isn't the utility—it's the terrain. Long A is a sloped corridor where three positions differ in height, cover thickness, and exposure area. This article doesn't debate whether to contest Long A; it only breaks down how these three slopes rewrite the duel ledger.
1. Entrance: Maximum Exposure, Shortest Retreat
The entrance (outside Long Doors) is the most exposed spot on the entire Long A. Standing here, your head, shoulders, and chest are simultaneously visible to the enemy at A Pit and Platform, leaving you a window of only fractions of a second to trade. Many players throw a "Long Doors flash" here to gain an early advantage, but they overlook one thing: the cover at the entrance is the door frame, and its thickness determines whether you can immediately retreat after peeking.
The narrow door frame means your "recovery window" is extremely short. Peek, shoot, and retreat must all happen in the same rhythm; a half-beat late and you'll be stuck at the edge of the frame taking a second bullet. So the correct use of the entrance isn't as a "duel spot" but as an "info spot": use a short flash to force the enemy to expose a body, gain information like "someone in pit/platform," then immediately fall back inside Long Doors and leave the trading to the ramp. Treating the entrance as a duel spot means trading the shortest retreat for the largest exposure—a bad deal on paper.
2. Ramp: Height Difference Redefines "First Move"
The ramp is the most underrated segment of Long A. Walking in from the entrance, the ground starts to rise; the height difference between you and A Pit shrinks, but the height difference between you and Platform grows. This asymmetric height difference directly redefines what "first move" means.
On flat ground, first move means seeing the enemy first. But on the ramp, first move means "your head enters the enemy's crosshair height first." If you hug the left side of the ramp, your head enters the pit enemy's view before your body; if you hug the right, your body exposes first and your head arrives later. That's why the same flashbang must be thrown differently on the ramp: left-side flashes are to suppress pit angles, right-side flashes are to suppress platform angles—the landing point and detonation height differ.
More critically, the ramp's slope makes your counter-strafe "soft." Stopping on a downward slope adds a forward inertia component compared to stopping on an upward slope, so your crosshair recovery is slightly slower. That tiny delay is a life-or-death line in Long A duels. So the correct way to play the ramp is to "hold high ground, fight low ground," not to "rush downhill for a duel." Holding the height difference is holding the first move.
3. Corner: Thickest Cover, Most Expensive Info
The corner (Long Corner) has the thickest cover among the three segments, and also the most expensive info. Standing behind the corner, you're almost completely enveloped by cover—the enemy can hardly see you, but you can't see them either. Info here can only be traded via "sound" and "utility."
The utility ledger at the corner is completely different from the entrance and ramp. Flashes at the entrance and ramp are for "buying a window"; flashes at the corner are for "buying time." A flash thrown toward A Pit from the corner isn't meant to blind someone, but to force the enemy to retreat into the pit, giving you a movement window from the corner to the pit entrance. The length of this window depends on the flash's detonation height and the enemy's retreat distance—the same flash thrown at the entrance yields a completely different profit structure.
Another detail: the corner's thick cover allows you to peek with "half a body." A half-body peek gives incomplete info but also exposes less area. Many players habitually peek out with their whole body at the corner, which throws away the thickest cover advantage for nothing. The correct use of the corner is "trade half a body for info, trade a full body for a kill"—the two must not be mixed.
4. The Three Slopes Together: Long A Is Not a Line, It's a Ledger
Looking at the entrance, ramp, and corner separately, you'll realize that Long A's duel logic isn't "whoever rushes first wins," but "whoever trades the right exposure area for the right info at the right position." The entrance trades short retreat for info, the ramp trades height difference for first move, the corner trades thick cover for time. Each segment has its own ledger; mixing them up leads to losses.
That's why pro teams rarely "push Long A in a single line." They take info at the entrance, pause at the ramp to confirm the height difference, and buy time with utility at the corner—the three rhythms are separate. The "five-man rush down Long A" you see in matchmaking often spends the entire ledger at the entrance, leaving no chips for the ramp and corner.
Finally, a note on utility "shelf life." The same flash thrown at the entrance versus the corner has a significant difference in detonation height, and the enemy's reaction time varies. When practicing Long A utility, don't just practice "throwing it in"—practice "where to throw, how high, and where to stand after throwing." When these three align, Long A truly becomes a playable corridor, not a straight line relying on luck.
