Just played the demo...it's pretty sad, really. Dead Space was such a promising new franchise.
Walk a straight line, shoot dumb-looking aliens, rinse, repeat, now get into shoot-outs with soldiers (what?), oh, and here's "a giant drill trying to kill me, lolz". Really lame.
I'm sure there will be lots of impressive scripted set pieces, even bigger/louder monsters than before, awesome explosions, great one-liners and cussing and bantering, suspenseful quicktime events, and everything else the Dead Space franchise didn't need.
I'm just going to pretend they never made a sequel to Dead Space!
