The Servant Grunts are monsterous Gatherers in Amnesia: The Dark Descent and are the weaker, more common type of the Gatherers. While not as powerful as the Brute, they are still a considerable threat in any appearance.
The Grunts cannot speak properly, owing to their inability to move what is left of their lower jaw and their apparent lack of a tongue. However, they are still capable of emitting a range of guttural growls, hisses and noises. Upon paying close attention, their growls sound like an attempt at normal speech, for if it notices the player, it may make a garbled attempt to say "I see you." Their visual and auditory perception appears to be unimpaired though, as they can easily notice Daniel if he is within viewing or hearing range. Staring at them will reduce sanity.
Sometimes while idle, Grunts can be seen and heard scratching themselves or whimpering, as if crying. Their initial growl is the signal that they hear Daniel and are coming to investigate. Daniel can withstand a couple of blows from a Grunt, and while they are difficult to outrun when they see Daniel fully, they do get confused fairly easily and thrown off the chase. Laudanum should be taken if a Grunt hits Daniel.
The intelligence of the Grunts is questionable, as they are rather inefficient at searching areas. They will also not notice Daniel if he is standing still and his head is not in view, unless there is a nearby light source such as a candle. They can even be thrown off if Daniel hides behind a door or other object, even if it is obvious (to a functioning human) that Daniel is there. It does seem that Grunts have some intelligence, though, and perhaps emotions; if Daniel makes a loud noise, the Grunt may turn to look in fright with its hands to its mouth before searching.
Grunts are repulsive, humanoid beings with seemingly pieced together bodies. Stitches and open scar-like wounds cover their pasty and stained skin, with bandages wound tightly around their feet and other parts of their torso. Their "skin" also functions as their clothing, as shown by the skirt-like protrusion around their waist and the sound of rubbing skin made when they walk. Their heads are malformed, with a distended jaw that hangs over their torso, stretched to an absurd length. There are clumps of hair still attached to their head. Their eyes are large, bulging and reptilian. The Grunts are missing their fingers on the left hand (though the concept art displays another set of digits); they are instead replaced by crude blades, which serve as the creature's primary weapon, and are stained with blood; this indicates that the grunt has either attacked another person or animal before, or that the blades were attached in such a way that it caused the grunt to bleed.
