They also deleted Naked Gun from the DNAD site prior to it being released. There is a lot of secrecy in the gaming world. A prime example is the recent Merlin Facebook game that was just released as a beta yet no one knew anything about. It wasn't until Fremantle started a 5 day countdown and then finally announced that Bossa Studios had developed the game that we knew about it. Prior to that there was not a word of Bossa Studios anywhere. It appears to me that Fremantle is controlling the PR piece about the game and wants it kept quiet, probably so they can build a lot of hype surrounding it when it gets close to release time.
I imagine that is the reason it disapeared from DNAD's sites and I like that Fremantle controls the PR machine, unlike Paramount who appears to be non-existent.
And recent DD suggests that DNAD is forging some stronger social networking/marketing relationships which may indicate a Facebook tie-in to the mobile game, or perhaps something else. I wouldn't be surprised if DNAD has been working with Bossa Studios to help develop the mobile game.
Good things coming IMO.
