Stug explosions can deal headshot damage when triggered above their targets, this also includes the blobs themselves hitting heads.
Notes
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.
When charging the weapon, it consumes pistol ammo constantly.
Though Status Chance displays to be 0%, it actually does deal Status proc towards its targets.
Trivia
The Stug is the second to be a very large sidearm in all secondaries. First is Acrid.
"Stug" may be understood as a Grineer word for "Slug", due to its apparent appearance.
The Stug derives its origin attack features from Unreal Tournament series' Bio-rifle, as primary attack includes shooting a regular bile of slime against a target, while its secondary attack features "charging" the slime in order to release a larger blob.
This is the second secondary weapon that has a Charge ability.
