It appears Microsoft is preparing a new game called Glacier Blast. The company this week filed an application with the United States Patent & Trademark Office (USPTO) for the name, covering "game software."
Microsoft also picked up a related domain name--www.GlacierBlastGame.com--at the end of March. The website currently redirects to a Bing search.
A Microsoft representative was not immediately available to comment.
Microsoft also recently filed a trademark application for game software called Marlow Briggs, though the company has not made any official announcements.
