At least part of Dead Space 2 takes place on The Sprawl, a city located on a moon off Saturn. Despite the seemingly gloomy ending of the original Dead Space, the sequel puts you once again in the high-tech suit of engineer and up-and-coming badass Isaac Clarke. It's unclear what Isaac is doing in the Sprawl, but things in the city have gone to hell and there are necromorphs everywhere. Worse news for Isaac: developer Visceral Games is upping the gruesome kills. Not just for how you dismember necromorphs, but in how they dismember Isaac.
One of the new enemies, the Puker, spits up a sickly fluid, has spindly arms and little desire to sign a peace accord. Use stasis (a power Isaac can deploy to slow time) so you can then pick off the Puker's limbs one carefully placed shot at a time. Just don't let it get too close or it will try and take a bite out of your arm. When it does, you'll be prompted to mash a button to escape -- by ripping the thing's head off.
You can use the javelin gun to nail enemies to the wall or the gravity gun to feel like you're Gordon Freeman. No word yet on whether or not you can chuck a toilet into a necromorph's head. The gravity gun also factors into puzzles which are back in Dead Space 2. You'll use the grav gun to pull down pieces of a high-tech contraption, disconnecting a power source to turn of zero gravity.
