We reported on Crackdown 2: Project Sunburst being pulled from the Marketplace just recently--a shock to many because even though the game had a few issues, it was still quite playable (and other games have the same or worse issues).
The trend of pulling troubled apps/games and then re-submitting them once they are fixed is becoming and unfortunate trend of late and there was no reason not to expect Project Sunburst to return at some point (heck, Twin Blades was gone for months...).
Unfortunately, it looks like the developers of Crackdown 2 have had enough and are throwing in the towel. From their Facebook page:
"As many of you know, Crackdown 2: Project Sunburst has been removed from the Xbox LIVE Marketplace on Windows Phone. If you purchased the game in the past 60 days, you will receive a refund credited to your account. Please note: with the removal of this game from the Marketplace, we will be discontinuing this page on Wednesday, July 27."
Ouch. This is a first for an Xbox LIVE game and quite a shame. Project Sunburst was the first game to feature asynchronous gameplay and use GPS/Bing Maps as the playboard--in other words, it was completely unique and imaginative, something that really stood out (even if gameplay was a bit boring after awhile). We really hope that this turns around but it sure doesn't sound like it. Sorry for the bad news folks, we're a bit crushed too.
