Not a rumor, it is online only.
Mixed feelings about that... It ensures the hacking and cheating will be GREATLY reduced if not eliminated all together, on the other hand, it forces you to be online even when playing solo.
That said, even in WOW, an mmorpg, I would play solo.
What it also provides is a truly seamless coop experience. Any of my friends can join my game and I theirs. I can also click a button to make it public if I choose.
I will run through the game at Normal difficulty once just to get a feel. Then I'll likely do the hardcore route as I did in TL.
And you'll be waiting a loooong while, TL2 will not be an xbox360 title. But it's going to be awesome and I will be nuying it at launch as well.
so, go get it!!! We need more exors!!!!
go!
