Thermal Thruster

From Team Fortress Wiki
Jump to: navigation, search

The Thermal Thruster is a secondary weapon for the Pyro. It is a team-colored, metallic jetpack with two rocket thrusters, one on each side (with the right thruster bearing the Pyro's emblem), and an enclosed yellow light on the top. When switching to the weapon, the backpack's thrusters fold outwards, exposing two handles which the Pyro holds in each hand. Switching away causes the thrusters and handles to fold inwards into the backpack.

The Thermal Thruster functions as a mobility tool, which stores two jetpack charges. Each charge is regained after 15 seconds. Additionally, the Thermal Thruster is locked at a 1.1 second holster duration, even with weapons that reduce draw/holster time such as the Degreaser.

On use, the Pyro performs an initial liftoff, sending it a short distance upwards. Shortly after, the Pyro will take off with a quick blast that launches the player in the direction they are aiming; the beginning of the jump also extinguishes any nearby teammates and pushes nearby enemies away. Upon landing, the Pyro will knock nearby enemies back; should the Pyro fall from a high enough altitude and land on an enemy (when the player makes a cartoony "falling" noise), the resultant stomp will deal 3x standard falling damage, much like the Mantreads. Depending on how high the Pyro jumps from when the Thermal Thruster is activated determines how powerful the knockback on enemies is.

Despite not being listed in the description, the player receives an added 30% knockback from all damage sources while this item is equipped, and takes reduced falling damage while using jetpack charges.

Using a second charge in midair is not possible unless the player buys an upgrade in Mann Vs. Machine.

Taunting with the Thermal Thruster equipped will perform the Gas Blast kill taunt.

Currently, the only way to obtain the Thermal Thruster is to complete Pyroland contracts 1-4, which grants an untradable and unmarketable Thermal Thruster as a contract reward.
