When using the alternate fire on the [[Flamethrower]] or [[Degreaser]], the [[Pyro]] is able to activate a '''Compression Blast''' (also known as an '''Airblast''') that can [[knock back|force]] enemies away and deflect [[Rocket]]s, [[Grenade]]s, [[Sticky bomb]]s, [[Baseball]]s, [[Jarate]], [[Mad Milk]], [[Flare Gun|Flares]], and [[Huntsman]] and [[Crusader's Crossbow]] arrows back at the enemy. Rockets fired from a Level 3 [[Sentry Gun]] can also be deflected. The compression blast will also instantly extinguish [[fire|burning]] team-mates when used on allies. These actions will exhaust 20 ammo per compression blast.

The '''Compression Blast''' (also known as the '''Airblast''') is the secondary fire for the [[Flamethrower]] and the [[Degreaser]]. The blast is a sphere-shaped discharge of gas that occurs directly on the end of the Flamethrower or Degreaser. It allows the [[Pyro]] to [[knock back|force]] enemies away, reflect almost all [[Projectile|projectiles]], and instantly extinguish [[fire|burning]] team-mates. Each use of this ability costs 20 ammunition from the Pyro's primary weapon.
  
This compression blast ability is incredibly useful. It allows the Pyro to blow away [[Sticky Bomb]] traps, separate a [[Medic]] from his patient, and hold his own against a [[Soldier]] or [[Demoman]] in close quarters. The blast is a sphere-shaped discharge of gas that occurs directly on the end of the Flamethrower or Degreaser. It is a momentary blast which require careful timing to execute. Another of Pyro's primary weapons, the [[Backburner]], lacks this ability.

==Deflection==
 
Rockets, jars, bottles, arrows, grenades, baseballs, and flares within the area of effect are redirected so that they will impact on the nearest surface that is facing the Pyro's direction. When these projectiles are deflected, they are not simply "bounced" as if from a mirror; the [[Pyro]] can actually aim them to a new location. For example, a deflected rocket is essentially stopped and "re-fired" from the player's current position which is aimed directly at a point on the nearest surface beneath the [[Pyro]]'s crosshairs. A skilled or well-positioned Pyro can even make rockets deflect at right angles to their original path.
 
  
Grenades and baseballs bounce away from the Pyro in accordance to the angle at which they were deflected. Aiming these deflected projectiles is more difficult, but their trajectory can be influenced somewhat by the Pyro's angle and position. Note that deflected grenades will gain a quick burst of speed while deflected sticky bombs will roll away from the Pyro.

When these projectiles are deflected, they are not simply "bounced" as if from a mirror; rather, the [[Pyro]] can aim them. Deflected projectiles are essentially stopped and "re-fired" from the Pyro's current position, aimed directly at the Pyro's crosshairs. A skilled or well-positioned Pyro can even deflect projectiles at right angles to their original path. Sticky bombs that are already on a surface will roll on that surface.
  
Deflected projectiles are considered to have been fired by the Pyro deflecting them for the purposes of friendly fire and kill awards. For example, a RED grenade will turn BLU when deflected and hurt any RED team players in the approximated area when it explodes. It can also hurt the [[Pyro]] who deflected it similar to how a Demoman can damage himself with his own Grenades. An exception to this rule is sticky bombs which can be pushed away, but they do not switch ownership. The only change to a deflected sticky bomb, besides their location, is that if the Demoman, who set up the sticky bomb, is blown up while the sticky bomb is in motion, it counts as a kill for the [[Pyro]] rather than as a [[suicide]]. Killing someone with a deflection produces a unique kill icon depending on the projectile.
+
Grenades and baseballs are not naturally given any additional vertical velocity when they are reflected. Aiming these deflected projectiles is more difficult, but their trajectory can be controlled by the Pyro's angle and position. They must be reflected upward in order to arc as they do when fired normally.
  
Deflected projectiles will always turn into Mini-Crits, although it is possible to get a full Crit depending on [[Crit]]ical status. Additionally, a deflected baseball will only [[stun]], as it would for the Scout who launched it.

If the Pyro is under the effects of the [[Kritzkrieg]]'s ÜberCharge, reflected projectiles will turn into Critical projectiles which makes it very risky for Soldiers or Demomen who are firing at this type of ÜberCharged Pyro.

Since [[April 28, 2010 Patch|April 28, 2010]], the compression blast was buffed to deal Mini-Crits on reflection unless the particular projectile was a full-Crit itself. Airblasting enemies into environmental deaths now awards the death credit to the Pyro (such as the pit in Steel or fall damage).

==Charging==
 
As of the September 30, 2010 Mann-Conomy Update, the Pyro (through editing the items_game.txt file) has the ability to charge airblast.
 
Although it has no effect on projectiles, charging can further the knockback dealt when airblasting enemies, depending on how long it is charged.
 
There is approximately a 5 second charging time for the maximum power achievable and the player cannot attack during the charging period.

==Strategy==
 
==Strategy==
*The compression blast can be used in two ways, aggressive and defensive.
+
* The reflective abilities of the airblast can be used defensively and offensively.
**Aggressive blasting includes blasting rockets, arrows, grenades, flares and sticky bombs back towards their original firers team. If timed correctly, the color of the projectile will change color and ownership as if the player had fired the projectile to begin with (the exception is the sticky bomb as the Demoman keeps control of it).
+
** Reflecting projectiles prevents them from harming your allies even if the projectile is not relocated. This is particularly effective against [[Grenade Launcher|grenades]].
**Defensive blasting includes moving stickies away from vital chokepoints (i.e. friendly Sentry Guns, the [[Cart]] track of a Payload map, control points, or gated exits). Moving the sticky bombs will help teammates progress through the area, and it will slightly delay the Demoman from returning to a vital holding point as they might think it is still secure.
+
** Returning projectiles deals significant damage to your enemies; it is probably the most damaging medium-long range attack you have.
***Also, remember that explosions will only hurt enemies and the player that reflected them. This will mean a team savvy Pyro can protect teammates from projectile fire in close quarters by airblasting the projectiles away. They will become friendly before exploding which will make them completely harmless to any teammates nearby. Watch out though, they will still inflict self damage to the Pyro.
+
* The airblast can be used to control enemy movement very effectively. Knock enemies away away from allies and health kits; knock them into environmental hazards if you can.
*Be aware of any [[Medic]] healing enemy Soldiers or Demomen, and try to re-direct explosives towards the Medic. If the Medic is using the [[Kritzkrieg]], then the Pyro is capable of reflecting the stream of Critical rockets or grenades back at the enemy. Additionally, if an allied Medic uses the Kritzkrieg, all reflects will be Critical hits, including attacks that normally cannot get Criticals (such as a Level 3 Sentry Gun's rockets).
+
** The knockback from the airblast is not cancelled by [[Medigun|ÜberCharges]]. This can be used to separate a medic from his patient, neutralizing the ÜberCharge.
*Also, take note of allies on fire since the compression blast can extinguish allies on fire. This is an often forgotten, but it is an incredibly useful tool in the Pyro's arsenal.
+
** Being airblasted is disorienting. Take advantage of this to make a quick escape.
*If an enemy begins to run towards a [[Health]] kit, the Pyro may airblast them away and possibly into teammate fire to finish them off.
+
** The knockback from the airblast can be used to deny a [[Scout]] their double jump.
*The Compression blast can also be used to delay enemies and keep them out of vital areas either by blowing them off ledges, pushing them into obstructions, or by [[Juggling]] them in the air,  usually done after they have been set on fire. This is to stop them being able to reach health kits. If the enemy is close to an instant death area (e.g. [[Saw blades]]), blasting enemies into them is a viable method of attack, and this method will earn the Pyro a "finished off" kill even if said Pyro did no damage to the player beforehand.
+
** [[Chargin' Targe|Charges]] can be turned aside with the airblast. Beware the extended melee reach that most Targe users have.
*Airblasting [[ÜberCharge]]d enemies is often a very useful strategy that can result in a wasted Über for the enemy team. A good way to halt an ÜberCharge is to separate the enemy Medic from their target. Oftentimes, the target will continue forward without realizing their Medic is out of reach until it is too late. Another viable strategy is to simply airblast either one or both of the enemies upward, then continue to airblast upwards as they come back down. This method is especially effective against enemy Pyro ÜberCharges due to the Pyro's lack of a sufficient long-range weapon. This strategy however is not as effective against Soldiers because they can easily shoot rockets at the player.
+
** [[Huntsman]] snipers cannot fire while airborne; the airblast allows you to put and hold them there.
*Airblasting unaware strong opponents such as the Heavy or the Soldier can be a good way to disorientate them which will allow teammates an opportunity to take them down. This combined with setting him on fire can be very effective since it will confuse the target long enough for the Pyro to move in and deliver a killing blow with the [[Axtinguisher]].
+
* Extinguishing [[Fire|burning]] allies can neutralize a significant amount of damage.
*With a moving enemy, the compression blast can be used to force them up into the air. They will not have nearly as much maneuverability in the air, and a Shotgun blast or two can stop them.
 
*It is possible to use a deflected Rocket to perform a [[rocket jump]] by aiming down, jumping, and airblasting at the right moment.[http://www.apple.com/games/articles/2010/06/teamfortress2/index.html]
 
*When standing above an enemy [[Soldier]] or [[Demoman]], a well timed airblast will block their [[rocket jump]] and push them back downward.
 
*Airblasting [[Jarate]] back to the [[Sniper]] that threw it or to other members of the enemy team can be a great asset to your team. This is also effective with [[Mad Milk]] from a [[Scout]], and it is a great way to get a quick heal.
 
*In order to successfully time a reflect for an arrow, rocket, or grenade, the player must time it shortly before the actual visual effect is within range. The visual effect is slightly behind where the actual projectile is, confusing some newer players.
 
*Use caution when using the compression blast against an enemy Sentry Gun; if it is being [[Wrangler|wrangled]], the Engineer controlling it may chose not to use rockets against the Pyro which deliberately refuse the Pyro the opportunity to do crucial damage to the Engineer.
 
*Using the compression blast is a good way to stop [[Chargin Targe|charging]] [[Demoman|Demomen]] in their tracks. Be wary of the [[Eyelander]]'s large range, though.
 
*Airblasting [[Spy|Spies]] into the air is a good way to prevent them from backstabbing allies.
 
*Airblasting [[Sniper]]s into the air is a great way to keep them from attacking.  Snipers using the Sniper Rifle will have their aim thrown off, and Snipers using the Huntsman will be completely unable to fire until they land.  This can be used to better predict when to try to deflect the Huntsman arrow, and just disorient Snipers in general.

Mmphpry!
The Pyro

The Compression Blast (also known as the Airblast) is the secondary fire for the Flamethrower and the Degreaser. The blast is a sphere-shaped discharge of gas that occurs directly on the end of the Flamethrower or Degreaser. It allows the Pyro to force enemies away, reflect almost all projectiles, and instantly extinguish burning team-mates. Each use of this ability costs 20 ammunition from the Pyro's primary weapon.

Deflection

The following projectiles can be reflected:


Projectiles within the area of effect are redirected so that they will impact on the nearest surface that is facing the Pyro's direction. When these projectiles are deflected, they are not simply "bounced" as if from a mirror; rather, the Pyro can aim them. Deflected projectiles are essentially stopped and "re-fired" from the Pyro's current position, aimed directly at the Pyro's crosshairs. A skilled or well-positioned Pyro can even deflect projectiles at right angles to their original path. Sticky bombs that are already on a surface will roll on that surface.

Grenades and baseballs are not naturally given any additional vertical velocity when they are reflected. Aiming these deflected projectiles is more difficult, but their trajectory can be controlled by the Pyro's angle and position. They must be reflected upward in order to arc as they do when fired normally.

Deflected projectiles are considered to have been fired by the Pyro deflecting them for the purposes of friendly fire and kill awards. For example, a RED grenade will turn BLU when deflected and hurt any RED team players in the approximated area when it explodes. It can also hurt the Pyro who deflected it, similar to a Soldier damaging himself with his own Rockets. The only exception to these rules is the sticky bomb. Although they can be pushed away, they do not switch ownership. The only change to a deflected sticky bomb is that if the Demoman who fired the sticky bomb detonates it while within the blast radius the Pyro will be credited for the kill.

Deflected projectiles will always turn into Mini-Crits, although it is possible to get a full Crit depending on Critical status. Additionally, a deflected baseball will only stun, as it would for the Scout who launched it. If the Pyro is under the effects of the Kritzkrieg's ÜberCharge, reflected projectiles will turn into Critical projectiles.

Killing someone with a deflection produces a unique kill icon depending on the projectile. Interestingly, there are a few inconsistencies for kill icons from reflected projectiles.

  • Sentry Gun rockets can be reflected and are quite powerful (doing 135-147 points of Mini-Crit damage to a player), but the kill icon used is the reflected rocket kill icon instead of their own.
  • Reflected Direct Hit and Black Box rockets do not have a unique icon of their own, but instead, the kill icon used is the generic reflected rocket icon.
  • Reflected Scottish Resistance stickies do not possess their own unique kill icon, and instead, the kill icon used is the generic reflected sticky mine icon.

Knockback

The compression blast will knock enemies back through the air by several feet which allows the Pyro to potentially juggle and finish off the player, or he could blast them off cliffs and capture points. This ability is highly useful for separating Medics and their patients and neutralizing ÜberCharged enemies. The knock back effect of the compression blast is disorientating though the enemy will still be able to attack.

Strategy

  • The reflective abilities of the airblast can be used defensively and offensively.
    • Reflecting projectiles prevents them from harming your allies even if the projectile is not relocated. This is particularly effective against grenades.
    • Returning projectiles deals significant damage to your enemies; it is probably the most damaging medium-long range attack you have.

    • The knockback from the airblast can be used to deny a Scout their double jump.
    • Charges can be turned aside with the airblast. Beware the extended melee reach that most Targe users have.
    • Huntsman snipers cannot fire while airborne; the airblast allows you to put and hold them there.
  • Extinguishing burning allies can neutralize a significant amount of damage.
