Multiplayer. That is coding team FASA's eggs and that is their sole, lonely, solitary basket. Because this, their E3-announced shooter Shadowrun, will not have a Campaign, Story or even single player mode, unless you count a few 'bot battles and a tutorial. Which we don't.
That being said, jettisoning a single-player game in favor of multiplayer only might not be the worst decision in the world when you consider the amount of balancing ahead of them: magic versus weaponry; Vista-powered PC versus Xbox 360; humans versus elf; troll versus dwarf; mouse versus pad; and framerate versus detail. As if to prove how difficult the title has been already, there are still only two versions of Capture The Flag to offer.
