Apparently, Visceral Games is making some announcement related to Dead Space 2 later this week. I know this because the studio said as much on its Facebook page. Technology! Somewhere in the picture above is a hint about said announcement.
Browsing through the comments, I learned a few things: the Unitology text supposedly means "ignition," Isaac is right-handed normally, so the image clearly confirms dual-wielding (clearly!), and lastly, some people seem to have -- seemingly out of nowhere -- associated multiplayer with the image.
Something tells me none of that stuff is quite ... uh, right? I think this situation calls for some good ol' crowdsourcing.
