You'd think everyone is used to it by now, and it looks as though they are. Halo 4 leaked late last week and, speaking to Polygon, 343 Industries' Frank O'Connor claimed he was not surprised by the situation.
"This is how surprised I am about this," he said, before shrugging his shoulders.
"There are people putting the whole thing on YouTube," he added. "Microsoft is addressing that a single case at a time, it just takes a little while to handle."
It's interesting: high profile video games are released during every holiday period, but the Halo series seems more susceptible to this sort of thing that, say, Modern Warfare or The Elder Scrolls. Are Halo games simply anticipated more by a specific subset of fans, or is there an issue?
