Microsoft is making another Crackdown game. This one's just called Crackdown, by the looks of it, and development's being handled by Dave Jones and - apparently - the Dundee-based firm Cloudgine. Jones created the first game in the series back at Realtime Worlds.
Announcing the game on-stage at Microsoft's E3 press conference, Jones promised campaign co-op and dedicated servers, and then showed a trailer that featured the Agency taking out a kingpin by hitting him in the face with a skyscraper.
So destructible terrain? Sounds like a good fit. More details when we get them.
