The GLOO Cannon is a versatile tool, which shoots quickly-hardening glue-like foam that expands as it hardens. The tool can be used for trapping foes where they stand, covering exposed flaming pipes and surging electrical boxes, or providing an interesting new path. Like the Huntress Boltcaster, the GLOO Cannon is not lethal and will not kill enemies other than Cystoids.
The GLOO Cannon is a "non-standard tech weapon" and therefore requires Lab Tech I and II to fully upgrade.
The GLOO Cannon is first found in the Neuromod Division right in front of the security booth, and is very hard to miss. The fabrication plan for the GLOO Cannon can be found in the Cargo Bay near a malfunctioning fabricator, while the fabrication plan for the ammo is found in the wall safe in Morgan Yu's Office on the top floor of the Talos I Lobby.
The GLOO Cannon is extremely versatile despite dealing no damage. Its most obvious use is immobilising hostiles for combat purposes or for scanning with the Psychoscope. The number of hits required to immobilise an enemy, how incapacitated the enemy becomes and how long it is incapacitated for depend on how large it is: a Mimic will be frozen entirely after a few shots, while a Phantom will only ever be slowed down by GLOO and can still attack. Enemies encased in GLOO take bonus damage, especially from the Wrench.
The device also has a lot of utility in simply getting around the station. Morgan can climb on GLOO "splats" easily using the ledge grab mechanic and paths can easily created either diagonally up walls or alternating sides of a shaft to reach inaccessible areas. GLOO can also extinguish some fires, plug holes in gas lines, temporarily stop electrical discharges from broken equipment, and seal breaches in the hull of Talos I. GLOO is also non-conductive and so can be used to create safe bridges over electrified floors.
It can also be used to create short-lived makeshift barriers to block doors or impede the path of smaller Typhon such as a Mimic who will have trouble traversing around the impedance, or in front of cystoids who will either be trapped or will detonate on the GLOO bubble, killing themselves in the process.
An important note is that GLOO splats will not form on glass or other GLOO splats.

- GLOO Cannon is one of the first weapons shown in Prey (2017) announcement trailer.
- The GLOO Cannon makes getting "out of bounds" in the game's maps extremely easy, to the point that the current speedrun record for Prey is seven minutes. (serious spoilers in this video, obviously)
