I'm playing Dead Space demo for the Xbox 360 and this thing is sick. And when I say sick I mean, dissolving-puppies-with-acid-and-feeding-poor-children-with-the-resulting-paste sick.
Anyhow, I'm using some weapon that cut the things into little pieces, but the little pieces jump at my neck and kill me, I shake them once but they attack me again.
What is the best strategy to kill these horrid undead meats?
