Extraction engages you further by giving you a wide variety of weapons with alternative firing modes and implementing a mini-game reload system that rewards you for being quick on the trigger.
This is inherently fun, and Dead Space's monstrous Necromorphs with their disgusting growths make for good targets. The general gist of the gameplay is that you move the reticle on the screen and blow away whatever it's covering. After shooting the ghouls this way, I couldn't go back to the functional but slower DualShock scheme. The Move controls are quick, easy and responsive. You can use a traditional controller to play Dead Space Extraction, but the game is designed to be played with the PlayStation Move.
Lopping off those limbs comes down to you and your aiming skills.
