I picked up a copy of OXM today before it got shipped out. They had a brief two paragraphs regarding Splinter Cell 4 online:
"The online portion of the game brings back the almost flawless portion of the versus mode, though now the teams can have up to three members. New moves for the spies and gadgets for the mercs (including a remote copter of sorts) will be included, as well as a fresh team-ranking system; perform well enough, and you can eventually reach an Instructor ranking, allowing you to take two novice players under your wing, thereby eliminating the severe imbalance caused by the mode's steep learning curve. A tweaked version of the co-op mode rounds out the online aspect of Double Agent.
Double Agent will also be available on the Xbox 1, though there are some key differences to the game, including varying level layouts, a few missing missions, a new spy-versus-spy multiplayer mode that will replace the spies-vs-mercs game, and a different co-op mode."
Despite being an entirely new experience, this is still Splinter Cell at heart, much like GRAW is still Ghost Recon. And that's what we love about Tom Clancy. He may not show up on time for the party, but he will bring the guests that everyone wants to meet and talk to. And his next-gen beauties are once again set to be the belles of the Xbox 360 ball."
I love how the article starts out mentioning the "almost flawless" online portion of the game. I conclude from that statement that Ubisoft is made of morphine. I suppose one thing is encouraging. It says that teams can now have "up to three members". I'm guessing that means we can play with two if we want to. However, if the maps are being designed for six players, well, that would suck.
I do inherit a small measure of satisfaction knowing that all the Xbox noobs won't even get SvM. Instead they get to play exclusive Spy vs. Spy. Oh goodie.
