Unfortunately, in posting this list, I did come across a few things I would have wanted to discover in the game itself. Speaking of which, I don't think this is considered as spoilers, but for Dead Space 3, players will be able to take on side missions. Unless I'm mistaken, this is a first for the series, as the two previous Dead Space games were very linear in where you can and can't go. I take it these side missions will probably be for John Carver and not for Clarke.
Lastly, everyone's favorite trinket — Peng — is once again in the game. Finding this bugger will net you the now-standard 10G's.
Overall, it's a pretty straightforward list, but seeing as Carver and Clarke are both suffering from the Marker's effects, I'm guessing the actual story will be anything but.
Dead Space 3 is scheduled to be out in February 2013 for the PC, Xbox 360 and PS3.
