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 wrench prevents the player from being able to haul buildings. Instead, pressing alt-fire or taunting (default key 'G') 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 the team's active respawn room. Doing so 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. The taunt cannot be activated if the player is in the air or in water.

Switching from this weapon to a different melee weapon will destroy all existing buildings.

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

Unused content

  • There is an idle particle designed for the tip of the electrode which is unused.
    • There is also an unused impact particle.

Bugs

  • Because the Eureka Effect's alt-fire 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).
  • The hauling HUD prompt is still present when this weapon is equipped.
  • If the player during the taunt receives any knockback, the player will be teleported into the spawn instantly.

Trivia

  • The weapon's alt-fire 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]
