Slider

The Slider is a boss that is thought to have been released along with the game.

Appearance
The Slider looks like an enlarged Green Runner with spawners on the sides and a trap launcher in the back.

Technical
''Not much is known about it. Like, at all. But this dude believes this using info from ToD and the looks...''

The Slider, much like the Vanguard, is a speedy boss. However, the Slider has two drone spawners in which it uses to attack enemies. These drones, considering it's a boss, probably have high penetration and damage.

Strategy
So, a recommendation would be to use Incognito to follow the slider until, it dies or the server restarts. If you are fortunate enough to find one, take pictures for the gallery.

If you wish to kill it, use Redistributor or high penetration tanks. Speedy bullet tanks may also work.

History
The boss idea of the Slider originated in a FANON "parody" of diep.io that went by the Tale of Diep.

Trivia

 * This is the second rarest boss in the game, the first being "Palisade."
 * It's pretty small.
