Xbox 360 version of Black Ops 2 leaks onto internet a week ahead

Now, YouTube is packed with gameplay videos, most of the new expanded Zombies mode. SPOILER WARNING: One of these is below.

Streams have also emerged. Responding, Treyarch design director David Vonderhaar took to Twitter to say: “If you are going to live-stream the game early, which I don’t remotely recommend, you could at least be good at it. :P”

Then, “I’m really glad people are excited for the game. Legit streams coming up later this week and early next. Watch this space.”

The news comes a week after reports claimed Black Ops 2 was sold early in Slovakia, although the Xbox 360 leak is thought to have originated from the US. Halo 4, out midnight tonight, leaked nearly a month before release.

Activision declined to comment when contacted by Eurogamer this morning.
