Pyro Troopers appear onward from Killzone: Liberation.
Armed with portable incendiary weapons, the Helghast Pyro Troopers specialise in clearing out enemy trenches and bunkers. Though they wear a brominated flame-retardant suit that offers a temporary shield from the flames, Pyro Troopers are still vulnerable to enemy fire.
The Pyro Troopers first appears in Chapter 3 while you are trying to infiltrate the base and kill Colonel Cobar.
The Pyro Trooper usually keeps his distance and rarely seeks or uses cover, instead seeking to rain deadly flames down upon his enemies with his Flame Thrower. The Flame Thrower is slow to fire and has a limited range, which the Pyro compensates for by arcing it up to increase the range and to circumvent cover. At close range the Pyro will begin to move backward to keep his distance and will never use melee attacks.
Despite looking frail and lightly armored, Pyro Troopers are surprisingly durable as they have 3 times as much health as the regular Helghast Assault Infantry. This makes them the most durable Helghast soldiers, save for the Heavys, encountered in Killzone 2.
Because of the Flame Thrower's long start up time and the fact that the Pyro Trooper does not utilize melee attacks, rushing them with knife attacks will bring them down quickly. However, killing them from a distance with headshots is often a much safer strategy.Killzone: Liberation and Killzone 2.
The pyro trooper also makes an appearance in Killzone Mercenary in contract 4. Like the pyro troopers in previous games, they have a VC1 Flamethrower and can ignite players with its fire. They have a large amount of armor, the best way to take them out is either by blowing up the gas tank on their backs or using explosives as they are almost impervious to small arms fire. The Brutal Melee can also be used on them. If you are ignited, running can douse out the flames.
