Interesting bit from the Guardian's article regarding multiplayer
"What we don't know about is multiplayer. The publisher is promising something very special, very different – but we're likely to see some similarities with GTA IV and Max Payne, with narrative and sandbox elements combining. Interestingly, when you bring up the character selection wheel in the bottom right corner of the screen, there's an icon for each of the lead characters, but also a fourth for multiplayer – so does that mean we'll be able to slip seamlessly from campaigns into competitive or co-op tasks? Will there be some interplay between the modes, as we have seen in titles like Dark Souls?
