The Sticky Grenade is the Gunner's default Throwable. It is a traditional "pineapple" grenade with an oversized ringpull, colored dark green. The grenade is covered in spikes which are retracted whilst in the Gunner's hand but stick out once thrown, hence explaining the grenade's sticky nature.
This grenade's fuse timer begins once it latches onto a surface. It can stick to almost any surface and will not roll. After the brief fuse timer, it will explode in a modest 4 meter radius for a rather high 130 damage. Most smaller creatures are as good as dead when they're stuck with a grenade.
Perhaps more interesting, however, is the grenade's Fear Factor effects: a target stuck with the Sticky Grenade is guaranteed to flee, and the resulting explosion will often scare away other creatures as well, resulting in a chain Fear effect. The explosion's radius doubles as the radius for the Fear chance.
This Fear mechanic has its pros and cons - it's great for forcing enemies (particularly Glyphids) to run away and give you and your team some space, but stuck targets can often run off on their own and die, minimizing the grenade's potential to clear out a full group of enemies.
This grenade can be quite useful against armored enemies with big weakspots - Glyphid Praetorians and Glyphid Oppressors are the most obvious choices. The explosion also has a good chance to break their armor too.
You get to carry six Sticky Grenades compared to the traditional four, meaning you can be a bit more liberal with their usage as a result
