Goo Gun

A gun that fires goo from carcasses

The Goo Gun is a weapon in ARK: Survival Ascended that turns corpses into ammunition. The game sums it up like this: "Uses harvested carcasses to create corrosive or bouncey balls of goo." You harvest a corpse with the gun (the ARK Wiki names Ctrl as the key), and once it holds goo there are two ways to shoot.

Firing modes and goo types

• Burst: the left mouse button sprays goo; a quick tap sends out just one small ball.
• Charged ball: holding the right mouse button grows a big ball, which reaches its largest size after about 2.5 seconds. Pressing primary fire releases it at whatever size it has reached.

The R key switches between two kinds of goo. Corrosive goo puts the Googed debuff on what it hits; the wiki lists the effect of that debuff as unknown. A charged corrosive ball clings to a target for some seconds, and one stuck to the ground attaches itself to any valid target that walks over it.

Bouncey goo pushes the shooter backwards, away from where the gun is aimed, and bigger balls push further. A bouncey ball left on the ground launches anyone who steps on it. Sticky balls of either kind vanish after roughly 7 seconds; a bouncey one also disappears once someone has bounced off it.
