With summer nearing its end in the northern hemisphere and spring starting in the southern hemisphere, the time has come for geeks worldwide to start preparing for Halloween. This incredible custom-built prawn assault rifle would be the perfect addition to any District 9 costume. Video after the break. Click here for more pictures.

The gun doesn’t just look awesome – it actually fires foam darts, thanks to its humble beginnings as a NERF blaster. It also has LEDs which light up when you pull the trigger – a touch that Munkle fully admits he stole from a different District 9 weapon.
