Dear Gears of War fans,
As most of you already know, Microsoft Studios has acquired the rights to the Gears of War franchise from Epic Games. Black Tusk Studios will take over development of the Gears of War franchise, including support of the communication channels such as the forums and social media pages.
On Monday, March 10th 2014 at 12:00 pm Pacific Standard Time (PST), the Epic Games Gears of War forums will be archived and locked, and the Facebook and Twitter pages will be transferred to Black Tusk Studios. Black Tusk Studios asks for your patience and support as they set up new forums for the Gears of War community, and encourage you to communicate with them over Facebook (this page) and Twitter (http://twitter.com/GearsofWar) during this forum transition over the coming weeks.
Epic Games would like to thank our fans for all the support and memories.
