Ruffian has detailed to VG247 the first pieces of info of the underground element of Crackdown 2 at a hands-on in Dundee last month.
Creative director Billy Thomson told us that there would be nine subterranean levels in the sequel.
"If you take one of the locations for a gang boss in the first game, most of them are… let me think of one location that’d be a good size. The Refinery, probably," said Thomson.
"A little bit smaller than the Refinery. And there’s, like, nine of them. It’s a big bit of gameplay."
Microsoft refused to go into details though on specific kits for the underground segments.
No date yet, we're afraid.
