“Cut off their limbs.” Words to live by, at least if you’re an engineer named Isaac. The message hurriedly scrawled in blood still provides the crux behind Dead Space’s satisfying gameplay. Its refreshing dismemberment-focused survival-horror action is one of the main reasons why I loved Dead Space and why I so hotly anticipate the sequel now. With such sadistic limb-severing love in mind, I jumped at the chance to try out the Dead Space 2 multiplayer beta. Think about it. An entire multiplayer mode built around shooting off limbs? Now that just sounds oh so gruesome and gratifying.
