A trademark for "Glacier Blast" was recently filed with the US Patent and Trademark Office by Microsoft. While no other information about it exists, the trademark was filed as game software. Microsoft also registered the domain glacierblastgame.com in late March, according to WhoIs records. The URL currently points to a Bing search.
Using our refined detective skills, we think it's possible that this piece of "game software" is a video game currently in development by Microsoft. With a name like "Glacier Blast," we'll be disappointed if the final product isn't an arctic naval combat game in which large icy masses shoot lasers at an enemy called "Global Warming."
