Reports tracing back to the Portuguese version of Eurogamer have surfaced with claims that a new sequel to Black was briefly posted on Criterion's official site and then quickly pulled from public view. Didn't see it myself, so we can't really confirm anything further, but it certainly sounds plausible.
The story claims that the game, titled Black: Second Mission, will be released in 2009 on PlayStation 3, PC, and Xbox 360. Sort of a boring name. They should just call it "Blacker." Or "Black 2: Bigger & Blacker." Or call it "Black Black" and get a tie-in with the Japanese candy of the same name.
It feels like ancient history now, but this isn't the first time a sequel to Black has been mentioned. It came up in EA financial reports given prior to the launch of the current generation of consoles as a game that was in development. Criterion has since gone on to deny that a sequel to its explosion-focused first-person shooter was in development, but it's always felt sort of inevitable. The game's release as a downloadable Xbox Original earlier this year only furthered the notion that we'd someday see a sequel.
The original Black was an interesting game, but one that felt short and a bit singular in its gameplay. The game's main trick was to almost always have the enemies standing near barrels or other explosive objects, turning the game into a kind of basic shooting gallery. Still, it had a great sense of a style and those explosions were pretty fantastic. I'd definitely be interested in seeing Criterion take another crack at it, especially if it received the long-term attention that the company's given to its most recent release, Burnout Paradise.
