Eureka Effect

Eureka Effect publicity blurb

The Eureka Effect is a melee weapon for the Engineer. It is a retro-futuristic pipe wrench with a team-colored handle and an atomic symbol etched into the top of it. A spiral antenna, not unlike a Tesla coil, is attached to the head. A switch near the top of the grip is connected to a red wire that is plugged into the bottom of the antenna.

Using this weapon will cause the Engineer to take twice as much time when upgrading and repairing buildings.

By pressing the reload key (default key: R), a menu will appear with options on where to teleport to. Choosing either will cause the Engineer to perform a taunt for approximately 2 seconds with the weapon, during which he hoists his wrench into the air and is struck by a bolt of lightning, causing him to be teleported directly to his chosen destination. Choosing the respawn room option gives him full ammunition, health and removes all effects caused by other players in the process and allows him to change his loadout, similar to touching a resupply cabinet. Choosing the Teleporter exit option will instantly move the Engineer to his Teleporter's exit, provided one has been fully built. A Teleporter entrance is not required for this option, and it will not cause the Teleporter system to need to recharge afterwards. Neither destination will leave the usual team-colored particle trails at the player's feet. The taunt cannot be activated if the player is in the air or in water.

Using the Pip-Boy will change the GUI similar to that of the destroy and build GUI's.

The Eureka Effect was later contributed to the Steam Workshop, at Valve's request.

July 24, 2014 Patch

  • Fixed a bug related to cancelling the Eureka Effect taunt and teleporting immediately.

Unused content

  • There are two unused particles; one of which is an idle particle designed for the tip of the electrode, the other is an impact particle.

Bugs

  • Because the Eureka Effect functions like an instant respawn, it will still replenish metal, ammo, and health in Arena mode and during Sudden Death, remove stored Revenge Crits if the Frontier Justice is equipped, and remove any crit boost status (such as crits during Humiliation) or debuff status (such as Jarate and being marked for death). This only applies if choosing to teleport to spawn, rather than the Teleporter exit.
  • If the player suffers knockback during the taunt, they will teleport before the animation completes.

Trivia

  • The weapon's teleportation ability bears resemblance to the Instant Teleport, a scrapped secondary weapon which would teleport the Engineer to his Teleporter Exit.
  • The name is derived from the term eureka effect, any sudden unexpected discovery, or the sudden realization of the solution to a problem.
  • This weapon is called the Wrenchmotron 600 on the Dr. Grordbort's website. The Eureka Effect is listed as an "electrifying taunt" there.[1]
