Despite Bungie's claims to the contrary, US magazine Game Informer has declared that its article on Halo: Forerunner is not, in fact, an April Fool's joke.
According to the article, Forerunner will feature "huge persistent worlds" built around a modified Halo 2 engine. It'll also have a co-op mode for up to four players.
A Bungie type dismissed the article as "an April Fool's gag" on the developer's forum - but in its latest issue, Game Informer says it's all true.
And that's not all - the mag is also claiming that Bungie's rumoured 'Project Orion' relates to a special ops team which is looking at the possibility of developing a massively multiplayer Halo game.
Sounds like fun - but is it fact or fiction? Well, looks like we'll just have to wait and see what turns up at E3 now, doesn't it...
