The Cloak Fighter is a light craft that has ability to Cloak itself, in which they will turn invisible for some duration, Cloak Fighter is armed with a Light Cannon instead of Launchers which has a higher velocity than rocket.
Cloak Fighter is also infamous for its "cloak nuke" strategy, in which players buy a nuke, fly a Cloak Fighter to an enemy Skyscraper or Technology Center and plant a nuke.
The Cloak Fighter's cloaking ability is limited by the fact that, once you cloak, you need to wait until the bar is filled up again to cloak, unlike in early 2023-era SC2, where the Cloak Fighter could cloak at any time, as long as the ability bar was not entirely drained.
