limited edition include 3D?

Yes, limited edition is essentially a normal edition with early unlocks EA is doing this with many of their games it's a marketing ploy.

But Crysis 2 comes with 3d in the limited edition for all 3 systems we do not know what is required but we guess you'll probs need a 3d tv.

All versions of Crysis 2 will have Stereoscopic 3D capabilities.

like the 2 before me said, all editions are 3D, it's an option in the game itself to use or not !
