Firing a sticky, toxic, explosive compound, the Stug Gel Gun offers multiple ejection modes, delivering maximum damage in all situations.
Stug is a Grineer pistol that deals Corrosive damage and was released in Update 11.5. It has a similar firing mechanism to Ballistica: quick tap fires a single weak "blob" and holding down the firing button charges the weapon, making the "blob" more powerful.
Area-of-Effect damage. 48.16% of base and any elemental damage will be used for the AoE damage.
Blobs do damage over time.
Blobs stack when shot onto each other, increasing detonation time and damage.
Blobs will adhere firmly to enemies.
Fast manual firing rate.
Explosions deal Status proc.
A polarity slot.
Very slow charge rate.
Unable to deal critical hit.
The steep arc and the low projectile speed severely limits accuracy. Also renders this weapon useless against long-ranged target. (However, the steep arc can be utilized to kill enemy units behind cover)
Can deal self-damage and Status proc to the user. The more blobs that are stacked, the more damage you will take.
Has very small explosion radius that does not increase when stacking blobs.
Ill-suited against Corpus, due to high chances of the exploding blob damaging their armored head instead (even if the blob is on their torso).
Blob cannot stack more than six blobs, if extra blobs are shot onto a full blob, it will stack but not increase damage.
Lephantis is 100% immune to this weapon due to explosions affecting the body rather than the weak points.
Stug explosions can deal headshot damage when triggered above their targets, this also includes the blobs themselves hitting heads.
Barrel Diffusion and Lethal Torrent will allow the Stug to build up blobs much faster, while the Lethal Torrent can increase firing and charging speed of the weapon.
It is not advisable to fight enemies in close range with this weapon, as it deals damage to the user, especially when equipped with Pathogen Rounds. The more blobs that are stacked, the more damage you will take.
The Stug can have three unique combination elementals, with Corrosive already provided, allowing Pathogen Rounds and Convulsion mods to be equipped separately for such combinations.
The Stug's shots will not just stick to enemies, but other players too. This lets you put them on another player for a little bit of quick melee defense (similar to Vauban's Teslas, but much shorter lived). Also the shots will stick to Loki's Decoy (and Saryn's Molt?) for a nice little trap.
The Stug is massive for a sidearm (the size of most primary weapons), extending from the kneecap of Oberon all the way up to the middle of the torso. This causes clipping issues, as the upper part of the gun can pass into the frame's torso when holstered.
Its Rate of fire belies its actual manual rate of fire, as the user can actually fire its non-charge shots very quickly. Therefore, the displayed rate of fire merely tells its slow charging rate.
Though Status Chance displays to be 0%, it actually does deal Status proc towards its targets.
Stug blobs explode when stepped on by anyone, including players.
Interrupting the charge (by Blocking, Wall-running, Falling... etc.) will waste the invested ammunition in that charge, preventing the weapon to fire the charged blob. It can also be interrupted by Reloading.
The expense of the charged shot determines how many manually fire blobs are fired at simultaneously.
The maximum charge of the Stug is 6, costing 6 pistol ammo.
The maximum size of the Stug blob is 10.
Barrel Diffusion (Level 4) releases a maximum charge of 10, due to the size hard limit.
Manual Barrel Diffusion shots deal a size of 2.
Having the weapon expend no ammunition while charging gives no supposed effects on the blob, such as using 2 pistol ammo to make a 6-charge will create a 2-charge blob instead.
Unlike certain other 'exotic' weapons (Ogris, Penta, Torid), the Stug will alert enemies when fired.
The Stug is the third of three very large secondary weapons. The first two would be the Acrid and the Ballistica.
"Stug" is likely taken from the WW2 German assault gun of the same name; this makes it the second Grineer weapon named after a military vehicle, the first being the Hind.
The Stug is clearly inspired by the Bio-rifle from the Unreal Tournament series, as it functions almost identically, thanks to its firing modes (shoot a single glob, or charge for a larger projectile) and projectile behaviour (slow and heavy, adheres to surfaces, delayed explosion).
This is the second secondary weapon that has a Charge ability.
While the game startup window (The one that lists recent updates) refers to the Stug as a Goo-gun, the shop calls it a Gel gun.
