Dead Space [$.99 / HD] is one of the seemingly billions of EA-published games on sale right now, and it's also received a new update. On both iPad and iPhone, Dead Space now supports EA's polarizing social UI, Origin. In more satisfying news, it also now supports Game Center integration by the way of leaderboards and apparently runs "smoother" thanks to some technical tinkering on the back-end.
If you didn't know, by the way, this portable spin on the ridiculously good horror-action franchise is also ridiculously good. And not in that Game Boy port kind of way, either -- this thing is a full, complete product that has its own feel, mechanics, pull. In other words, it easily stands on its own. You should check it out while it's on sale for $.99 and get familiar. We'll be talking about it again this year.
