The first in-game Halo 4 screenshots have appeared online via Gamerlive.tv but they reveal no gameplay content. The game's described as "the dawn of a new trilogy" and its developers have claimed they're taking it "back to what made Halo 3 amazing".
Microsoft's been leaking all over the place this weekend, with Forza Horizon, Fable Heroes and Fable: The Journey media all appearing online. You could say this could be some kind of marketing..?
