The release is only 16 days away! I am loooongiiing! I finished the first game twice in a row, and I played through it all again some week ago just because of this game ^^
One thing that is interesting is that the Rivet Gun is described as being fast and accurate in Dead Space 2. If anyone has played Dead Space: Extraction, the Rivet Gun was ANYTHING but fast. I would raise a stink about the firing speed on the rivet gun, but then again, Isaac could be using an upgraded model designed to fire rivets at a faster speed.
Of course, the Rivet Gun in DS2 is only usable if you preorder the game. ._.
