Ding dong dash
Other names: none.
After initiating an attack, it can be prudent to withdraw and regain stealth, particularly when outnumbered or outgunned. The ding dong dash is a means of reducing the damage inflicted on the retreating party via a sudden surprise attack on enemy communications immediately prior to the escape. This takes the form of a piercingly loud burst of comms feedback that, when deployed in time with a rocket jump, can be very effective at spoiling enemy aim.
