The AMR-B05, also known as "The Repeater," is a fully-automatic Prawn weapon. The weapon functions as an assault rifle.
The tubes down the side each discharge an explosive burst of gas one after the other down the length of the barrel behind the projectile - a linear accelerator gun, similar to a rail gun. Of course it would fire these all rapidly to get a high rate of fire.
- Christopher Johnson used this when he was storming the MNU building with Wikus to retrieve The Fluid.
- A weapon of this design is part of the onboard weaponry of the Exosuit.
- A second variant of the weapon (pictured right) was also created by the props department, although it does not appear in the film other than as background in some shack scenes. According to published materials its functionality is identical to the standard version, but it carries an enlarged magazine and is for use by Exo Suits.
