With these weapons, the best place to aim is the neck, especially for the Line Gun. Weapons covering large areas like the Force Gun, Line Gun, and Flamethrower are about the best weapons to use against the Grabbers.

While using precision weapons like the Pulse Rifle and Contact Beam, this is the best place to aim at.

The biggest target on the Grabber is its head.

Keep an eye out for bodies that lacks a head, or the head is stragely propped/twisted in an odd angle, as these are the most likely to turn.

Grabbers can spawn from any waterborne corpse.

Given the overall small size of the Grabber, weapons like the Plasma Cutter and Rivet Gun are not very effective.

Although they do not appear to be able to move in the game, it is possible that they might be able to drag themselves into suitable ambush positions. It is unclear whether the bodies were infected in the drains and simply mutated to best suit their needs, or if they were infected elsewhere and then moved to the drains by other Necromorphs. Several more Grabbers are found throughout the drainage system, surprising the team by lying in wait before lunging up from beneath the surface of the murky water. Once it is dispatched, Warren Eckhardt states that the creatures are adapting to their surroundings. The Grabber then splits its human head in half and begins to shake McNeill's head violently with its tongue flailing around. Once he is closer in range, though, the Necromorph's head begins to shake before whipping upwards and startling the survivors. They first appear in Chapter 6 of Extraction when Nathan approaches a corpse, partly submerged in the water, which does not appear to have been infected. They seem to continue the purpose they were supposed to have in Dead Space.

While these disturbing creatures were not in Dead Space, they do appear in Dead Space: Extraction. In this case most of the main body's mass has been transformed to make and store the Grabber's extremely long, muscular neck and spinal blade. Consisting of a seemingly inconspicuous human corpse, albeit slightly damaged, the Grabber uses the element of surprise by extending the mutated corpse's head an impossibly long distance towards the player and latching on to the player to either hold them still and distract them (not to mention disturb them), or drag them towards the Grabber's body while a serrated blade (formerly the corpse's spine) bursts out of the same orifice to kill the player. The Grabber is a Necromorph whose design was ultimately scrapped for the inclusion in Dead Space.
