YES!!!!
The Dribble is what we called it. Essentially, the blue light that leads your way in the first Dead Space. (Haven't played the second.)
It was just like he drops his hand, and the blue light guides the way, so my brother called it the Dribble, and we all picked it up without hesitation. It was loved dearly, though we got mad at it when it wouldn't quite tell us enough. Still though, the dribble is a more memorable character than most of the others. Even some of the weapons couldn't compare to it.
